Right - Western side of the Eglinton Avenue Underpass (Site #37-803) below the southbound lanes of Hwy 427 in 1980. This is one of eight underpass structures carrying Eglinton Avenue through the complex Hwy 427 and Hwy 27 Interchange in Toronto. When the western leg of the Toronto Bypass was originally built through this area in 1954, Eglinton Avenue (then known as Richview Sideroad) passed over the freeway via a single overpass structure. During reconstruction of this interchange in the late 1960s, the original overpass across Hwy 27 was demolished and replaced with the various underpass structures seen today. See an Enlarged Photo Here. Photo taken on July 14, 1980.

Above - Western side of the Eglinton Avenue Underpass (Site #37-806) below the ramp from southbound Hwy 27 to southbound Hwy 427 in 1980. This cluster of four closely-spaced structures carries both the northbound and southbound ramps between Hwy 27 and Hwy 427 across Eglinton Avenue, along with the northbound Hwy 427 ramps to Eglinton Avenue East and Eglinton Avenue West. The original grade separation between Richview Sideroad and Hwy 27 once stood roughly at the photographer's vantage point. The old overpass was demolished in 1970, after the new route for Eglinton Avenue through the interchange was completed and opened to traffic. See an Enlarged Photo Here. Photo taken on July 14, 1980.

Left - Facing south along the southbound Hwy 27 ramp to southbound Hwy 427 approaching the Eglinton Avenue Underpass (Site #37-806) in Toronto in 1980. This ramp becomes the southbound Hwy 427 Collector Lanes just ahead. A vintage yellow-and-black "This Lane Ends" sign can be seen at right. Although commonly seen along Ontario's freeways up until the 1980s, these unconventional warning signs were phased out and replaced with the current diamond-shaped warning signs that we see out on the highways today. Instead of having the "Lane Ends" message conveyed in text, newer signs show this information graphically. Over the decades, traffic engineers have attempted to minimize the use of text on signs whenever it can be substituted by a commonly-understood graphical representation of the intended message.

Right - Facing south towards the Queen Elizabeth Way along the northbound Hwy 427 Collector Lanes from the Hwy 5 (Dundas Street) Underpass (Site #37-865) in 1980. During the construction of the complex freeway in the late 1960s, a rigid concrete pavement was laid along Hwy 427. Over the years, an asphalt overlay was constructed over the original concrete surface in order to create a composite pavement structure. This section of the concrete was topped up with hot-mix asphalt during a highway rehabilitation project in 2013-2014, under Contract #2011-2042. See an Enlarged Photo Here. Photo taken on August 27, 1980.

Right - Facing north along the southbound lanes of Hwy 427 at the Fasken Drive Underpass (Site #37-986/2) in 1980. This interesting photo shows the newly-completed freeway on the southern approach to the Hwy 409 & Hwy 427 Interchange in Toronto. This section of Hwy 427 was constructed under Contract #1977-46. The new interchange at Hwy 409 and its approaches were completed in October 1978. When this interchange was first constructed in the late 1970s, southbound Hwy 427 traffic wishing to access Hwy 409 had to turn left across the northbound lanes of the highway through a signalized intersection. Note the warning sign in the background advising motorists of the upcoming traffic signals at the Hwy 409 on-ramp. This was one of two signalized intersections along Hwy 427. The other signalized intersection was located north of Rexdale Boulevard at Morning Star Drive in Malton. Both traffic signals were removed from Hwy 427 during highway improvements carried out in the 1990s. See an Enlarged Photo Here. Photo taken on September 19, 1980.

Right - Western side of the Hwy 409 Underpass (Site #37-985/2) at Hwy 427 in Toronto in 1980. This freeway grade separation was built under Contract #1977-46 as part of the final phase of the new freeway link between Toronto International Airport and Hwy 401, via Hwy 409. The new freeway was completed and opened to traffic to in October 1978, and provided greatly-improved access to the airport from the east. Noticeably absent in this photo is the high-level flyover from southbound Hwy 427 to eastbound Hwy 409, which wasn't built until the early 1990s. See an Enlarged Photo Here. Photo taken on September 19, 1980.

Left - Facing east along Hwy 409 at the Hwy 427 Interchange in Toronto in 1980. As initially constructed in the 1970s, the median along Hwy 409 had a double steel beam guide rail barrier. This type of median barrier system was commonly used along freeways with narrow medians up until the late 1970s, when concrete barriers of various designs became the preferred treatment for narrow freeway medians.

Right - Facing north along the northbound lanes of Hwy 427 at the Hwy 409 Underpass (Site #37-985/1) in Toronto in 1980. During the early 1990s, a new flyover structure was built to carry traffic from southbound Hwy 427 to eastbound Hwy 409. At the time this photo was taken, all southbound Hwy 427 traffic wishing to access Hwy 409 had to do so across the northbound lanes of the highway at a signalized intersection. Initially, this signalized intersection operated without too much difficulty, since traffic volumes on Hwy 427 were fairly low at the time. By the early 1990s, however, traffic volumes on Hwy 427 had more than tripled since this interchange's initial construction in 1977-1978. When the new flyover ramp was completed and opened to traffic in 1992, the old traffic signals were decommissioned and removed. See an Enlarged Photo Here. Photo taken on September 19, 1980.

The on-ramp from westbound Eglinton Avenue can be seen joining into the westbound Hwy 401 Express Lanes at right. Originally, this was a two-lane on-ramp. During the widening of Hwy 401 at Hwy 427 in 2002-2003, the Eglinton Avenue ramp was reduced to a single lane in order to allow for the construction of a fourth through lane on westbound Hwy 401. See an Enlarged Photo Here. Photo taken on November 5, 1980.

Right - Advance overhead guide sign for the Hwy 427 and Renforth Drive Exit on eastbound Hwy 401 in 1980. These two closely-spaced exits were essentially the first phase of the Express-Collector Lane System along Hwy 401 through Mississauga. Note that this exit was once signed as "Interchange #45". In the early 1960s, an exit numbering system was introduced along Hwy 401. Under this numbering system, interchanges were numbered sequentially from Windsor to the Quebec Boundary (west to east). Unfortunately, this sequential exit numbering system began to cause problems as new interchanges were constructed along Hwy 401 in subsequent years. Suffixed exits like Interchange 36A, for example, had to be implemented in order to prevent advancing all of the existing freeway exit numbers ahead by one. This problem was solved in 1982, when a new distance-based interchange numbering system was introduced on Ontario's freeways. Interchanges were numbered based on their approximate mileage point instead of their sequence. This new system allowed additional interchange numbers to be easily added in the future, since there would generally be a distance offset between a proposed and existing interchange.

Right - Approaching the Renforth Drive Interchange on the eastbound Hwy 401 Collector Lanes. When the Collector Lanes were first built here in 1971, Lane #4 exited to Renforth Drive, while Lanes #1 to #3 continued through to Hwy 427 and the Airport Expressway. When Metro Toronto decided against building the Richview Expressway along Eglinton Avenue, it changed the traffic patterns at the Hwy 401 & Hwy 427 Interchange. As a consequence of that decision, far more traffic began using Hwy 427 South than highway engineers had initially anticipated when the Hwy 401 & Hwy 427 Interchange was designed in the late 1960s. In order to provide more lane capacity in the eastbound Hwy 401 Collector Lanes, the lanes at the Renforth Drive exit were reconfigured during a highway widening project which began in 1983. Accordingly, Lane #4 was extended through to Hwy 427, so that four through lanes were provided on the approach to Hwy 427 instead of the original three through lanes seen here. See an Enlarged Photo Here. Photo taken on November 5, 1980.

When the Airport Expressway was originally constructed in the early 1960s, the freeway came to an end at Dixon Road. Constructed under Contract #1962-267, this structure was initially built to carry both northbound and southbound Airport Expressway traffic. A twin structure was built under Contract #1981-46 to carry the future northbound lanes of Hwy 427. The twin bridge can be seen under construction on the far side of the underpass in this photo. See an Enlarged Photo Here. Photo taken on June 24, 1982.

Above - Facing south along the Airport Expressway (Hwy 427) at the Dixon Road Underpass in 1982. The photo shows the original cross section of the Airport Expressway through the Dixon Road Interchange, with northbound and southbound lanes separated by a narrow concrete curb median. As originally constructed in the 1960s, the Airport Expressway narrowed back to two lanes north of the Dixon Road Interchange and continued north towards Malton as Indian Line. However, once Hwy 427 was extended north to Rexdale Boulevard in the late 1970s and early 1980s, the Dixon Road Underpass became a serious traffic bottleneck. Accordingly, the structure seen here was converted to carry southbound traffic only, while a new twin structure was built beside it to carry all northbound lanes of Hwy 427. See an Enlarged Photo Here. Photo taken on June 24, 1982.

This structure was built under Contract #1981-46 and was completed in 1982. Following completion of this new structure, all Hwy 427 traffic was temporarily diverted onto the new bridge. The old structure over Dixon Road was temporarily closed for rehabilitation and removal of the old concrete curb median. Once rehabilitation work was completed on the existing Dixon Road structure, the bridge was reopened to carry southbound Hwy 427 traffic only. Northbound traffic began to use the new twin structure exclusively. See an Enlarged Photo Here. Photo taken on June 24, 1982.

Right - View of the southbound lanes of Hwy 427 at the Hwy 409 Interchange in 1982, showing the traffic signals at the eastbound Hwy 409 on-ramp. While it might see hard to believe, there was once a signalized intersection on Hwy 427 at the Hwy 409 Interchange for many years. While southbound traffic faced a perpetual green indication at this traffic signal, northbound Hwy 427 traffic had to periodically stop to allow southbound Hwy 427 traffic bound for the eastbound Hwy 409 on-ramp to cross over the northbound lanes. At the time the Hwy 409 & Hwy 427 Interchange was initially built in the late 1970s, traffic volumes were low enough that this signalized intersection likely operated okay for the first few years. However, as Hwy 427 was extended northwards towards Woodbridge, traffic volumes along the corridor quickly grew. By the 1990s, the traffic signals at the Hwy 409 on-ramp had become a serious bottleneck. The on-ramp to Hwy 409 was rebuilt as a high-level flyover in the early 1990s under Contract #1990-32. Once the new flyover opened to traffic in mid-1992, these traffic signals were decommissioned and removed from the highway. See an Enlarged Photo Here. Photo taken on September 13, 1982.

Left - Overhead freeway guide signs on westbound Hwy 401 at the Dixon Road Interchange in Toronto in 1984. Note the older pre-advance guide sign for the upcoming Hwy 427 Interchange, which contains the unusual phrase "EXIT RIGHT" along with the distance to the exit ramp. As part of an effort to make freeway guide signs less "wordy" in complex driving environments, this phrase is no longer used on freeway guide signs anymore. Motorists anticipate that the vast majority of freeway exit ramps they encounter while driving will appear on the right-hand side of the freeway, so this phrase was dropped from newer signs as it was considered to be unnecessary information. This phrase was likely included on this particular sign as the original exit ramp to southbound Hwy 427 from westbound Hwy 401 did indeed develop and exit on the left-hand side of Hwy 401 at one time.

Right - Overhead freeway guide sign on westbound Hwy 401, marking the exit ramp to southbound Hwy 427 in 1984. When Hwy 401 was extended westerly from Toronto towards Milton in the late 1950s, the extension resulted in an exit ramp to Hwy 27 (later known as Hwy 427) which developed on the left-hand side of the freeway. This ramp configuration created a lot of operational problems at this interchange. When the interchange was reconstructed in the late 1960s and early 1970s, this exit ramp was changed to the right-hand exit we see today. See an Enlarged Photo Here. Photo taken in July 1984.

Right - Overhead freeway guide sign at the exit to Eglinton Avenue on eastbound Hwy 401 at the Hwy 427 Interchange in Toronto. The structure in the background carries the southbound lanes of Hwy 427 across Hwy 401, along with the southbound Hwy 427 exit ramp traffic to Eglinton Avenue. This structure was built under Contract #1970-129 and was completed in 1971. When the Hwy 401 & Hwy 427 Interchange was originally being designed, it was anticipated that a new municipal expressway known as the Richview Expressway was going to be constructed by Metropolitan Toronto easterly from here via Eglinton Avenue. Accordingly, this exit ramp was designed as if it were to one day become a freeway-to-freeway ramp movement. However, the Richview Expressway was never built, which left behind this interesting ramp connection to Eglinton Avenue which was designed to freeway standards. See an Enlarged Photo Here.

While the twin highway was already in operation at the time this photo was taken in the Summer of 1985, note that the east-to-north ramp from westbound Rexdale Boulevard to northbound Hwy 427 in the foreground was not yet completed to its ultimate configuration. While this ramp was open for a number of years following the Rexdale Boulevard Interchange's construction in 1978-1979, the original ramp wasn't compatible with the future Hwy 427 lane configuration to the north of the interchange. For a while, the Rexdale Boulevard Interchange was operated as a "Parclo A-2" on the eastern side, with all traffic bound for northbound Hwy 427 sharing a single ramp in the southeast interchange quadrant.

Left - Facing south along the northbound lanes of Hwy 427 at the Woodbine Access Road Underpass (Site #37-983/1). When this section of Hwy 427 was first built in the late 1970s under Contract #1978-111, the freeway had two lanes in each direction (4 lanes total). The highway was subsequently widened in stages to six lanes starting in the 1990s and then to eight lanes in the 2010s. See an Enlarged Photo Here. Photo taken on September 18, 1985.

In the background, an older angled advance exit sign for Hwy 401 can be seen over the northbound lanes of Hwy 427. These angled signs were designed to "point" towards the direction of the upcoming exit ramp or transfer. On complex freeways such as Hwy 427, these signs were very helpful in differentiating left-hand exit ramps and transfer points from those appearing on the right-hand side. These angled signs were phased out as part of a modernization of freeway signing practices during the 1990s. See an Enlarged Photo Here. Photo taken on September 20, 1985.

Right - Southern side of the Burnhamthorpe Road Overpass on Hwy 427 in Toronto in 1988. An overhead bridge-mounted guide sign over the northbound Hwy 427 Express Lanes advises motorists of the upcoming transfer to the Collector Lanes, which provides access to Hwy 27 and Eglinton Avenue. Interestingly, Hwy 27 is spelled out in text on this sign rather than the typical route number displayed inside a crown. It is probable that this was due to space constraints on the signboard. While signs can be manufactured in all sorts of shapes and sizes, the sign support structures they get affixed to always have a maximum loading limit. Once a sign support structure has been installed, it is very costly to increase a signboard size as a retrofit. Often, it means that a new sign support structure is required to handle the increased signboard load. See an Enlarged Photo Here. Photo taken on September 1, 1988.
