Left - View of Hwy 401 approaching the Mill Street Interchange in Newcastle in 1995, facing west from Graham Creek. This great photo shows the original four-lane cross section of Hwy 401 through Newcastle, prior to the highway's widening in the late 1990s. This section of Hwy 401 was widened from four to six lanes under Contract #1997-800. See an Enlarged Photo Here. Photo taken on June 12, 1995.

Right - Looking through the Graham Creek Culvert (Site #21-194/C) on Hwy 401, located just east of the Mill Street Interchange in Newcastle. This large concrete barrel arch culvert has a diameter of 40 feet and was among the first structures built along the new extension of Hwy 401 from Newcastle to Port Hope. The Graham Creek structure was built under Contract #1957-280 and was completed in 1958. See an Enlarged Photo Here. Photo taken on June 12, 1995.

Left - View of the eastbound Hwy 401 directional exit ramp to northbound Yonge Street (Hwy 11) in Toronto, where it passes below the structure (Site #37-342) carrying the exit ramp from westbound Hwy 401 to Yonge Street. This directional exit ramp was built this way in the mid-1960s due to the adjacent Hogg's Hollow Bridge and the skew of the Yonge Street crossing, which made the construction of a conventional exit ramp to Yonge Street very challenging and costly. This directional ramp also provides a high-capacity facility to service the heavy traffic volumes exiting from eastbound Hwy 401 to northbound Yonge Street. See an Enlarged Photo Here. Photo taken on June 14, 1995.

Right - Facing west along the exit ramp to Yonge Street (Hwy 11) from westbound Hwy 401, where it passes over the directional exit ramp from eastbound Hwy 401. The Yonge Street (Hwy 11) interchange on Hwy 401 was initially built in the 1950s as a full eight-ramp cloverleaf - and a very constrained one, at that. The original cloverleaf interchange began to exhibit operational problems in the years following its opening, due to quickly rising traffic volumes and poor ramp geometry. As part of the reconstruction and widening of Hwy 401 during the 1960s, the Yonge Street Interchange was redesigned to the layout seen today. See an Enlarged Photo Here. Photo taken on June 14, 1995.

Left - Facing west along the eastbound exit ramp from Hwy 401 at the Yonge Street (Hwy 11) Interchange in Toronto. After diverging from Hwy 401, this exit ramp forks into two ramps - the two-lane directional ramp to northbound Yonge Street and a single-lane ramp to southbound Yonge Street. The high-level viaduct structure over the Don River at Hogg's Hollow can be seen in the background just beyond the highway curve. See an Enlarged Photo Here. Photo taken on June 14, 1995.

Right - Southern side of the Yonge Street (Hwy 11) Underpass (Site #37-340) below the directional ramp from eastbound Hwy 401 to northbound Yonge Street in Toronto. The Yonge Street Interchange is rather complex, with four different grade-separated crossings. Three of the grade separations are situated along the directional West-to-North ramp. This structure over Yonge Street also carries a pedestrain sidewalk between the east and west sides of Yonge Street. See an Enlarged Photo Here. Photo taken on June 14, 1995.

Left - Facing west along the on-ramp to the westbound Hwy 401 Express Lanes from northbound Allen Road in Toronto. This flyover structure (Bridge #4 - Site #37-285) carries the on-ramp from northbound Allen Road across the westbound Hwy 401 Collector Lanes. At the time this photo was taken in 1995, this bridge also crossed over a westbound Hwy 401 Express-to-Collector Transfer, which has since been removed from the highway below. Minor repairs to this structure were carried out under Contract #1994-69. See an Enlarged Photo Here. Photo taken on June 14, 1995.

Right - View of the Allen Road Interchange on Hwy 401 in 1995, as seen from the flyover across the westbound Hwy 401 Collector Lanes (Bridge #4 - Site #37-285). Note the now-removed Express-to-Collector Transfer in the background, which essentially only served the Keele Street Interchange. As a result, it was one of the more lightly-used transfer points along Hwy 401 across Toronto. This transfer was reversed a few years after this photo was taken, so that it carried traffic from the westbound Hwy 401 Collector Lanes to the westbound Hwy 401 Express Lanes. Prior to this change, motorists entering westbound Hwy 401 from the Bayview Avenue, Yonge Street and Avenue Road Interchanges were not able to access the Hwy 401 Express Lanes until "The Basketweave", located between the Keele Street and Hwy 400 Interchanges. See an Enlarged Photo Here. Photo taken on June 14, 1995.

The complex interchange at Yonge Street was built as part of a multi-year reconstruction and widening project. Under Contract #1965-131, an Express-Collector Lane System was introduced along Hwy 401 from Hogg's Hollow to a point just east of the Bayview Avenue Interchange along with a new higher-capacity interchange at Yonge Street (Hwy 11).

When the highway was initially widened to 12 lanes through the Yonge Street Interchange in the mid-1960s, the eastbound Hwy 401 Collector Lanes had only two lanes through the Yonge Street Interchange. During subsequent reconstruction work, an additional eastbound lane was carried through the interchange. See an Enlarged Photo Here. Photo taken on July 12, 1995.

Left - Eastern side of the Neilson Road Overpass on Hwy 401 in Toronto. This was a new arterial road interchange built along Hwy 401 in the late 1970s under Contract #1979-84. When the Toronto Bypass was first built through Scarborough in the 1950s, there were no interchanges or grade-separated roads crossing Hwy 401 between the Hwy 48 (Markham Road) Interchange and the Littles Road Interchange (today's Morningside Avenue). At the time this photo was taken in the Summer of 1995, the Hwy 401 Express-Collector Lane System had been completed and fully opened to traffic. Previously, the Hwy 401 Express Lanes came to an end just west of the Neilson Road Interchange. See an Enlarged Photo Here. Photo taken on August 1, 1995.

Right - Facing west across the Hogg's Hollow Bridge (Site #37-203/4) on the westbound Hwy 401 Express Lanes in Toronto. This photo was taken on a Sunday during a full closure of the westbound Hwy 401 Express Lanes for rehabilitation and maintenance. Weekend closures of the various roadways within Hwy 401's Express-Collector Lane System were routinely done during the 1990s. Note how light the traffic is in the adjacent westbound Hwy 401 Collector Lanes, despite the westbound Hwy 401 Express Lanes being fully closed to traffic. It certainly speaks to the comparatively low traffic volumes on Hwy 401 at that time! If executed today, a daytime closure like this one would result in severe congestion - even on a Sunday. An overhead sign marks the upcoming Hogg's Hollow Express-to-Collector Transfer, which services Avenue Road (Hwy 11A) and Bathurst Street. At the time this photo was taken in 1995, westbound Hwy 401 traffic bound for Keele Street did not have to use the upcoming Hogg's Hollow Transfer. A second Express-to-Collector Transfer once existed within the Allen Road Interchange which serviced Keele Street, although it has since been closed to traffic. Today, traffic bound for Keele Street needs to transfer at Hogg's Hollow. See an Enlarged Photo Here. Photo taken on September 10, 1995.

The original lanes of Hwy 401 crossed Duffins Creek on two twin structures that were built as part of the Toronto-Oshawa Dual Highway in 1941. Both the eastbound and westbound spans were widened in 1973, in order to permit the construction of an extra lane in each direction. The newer widened span is visible at right, while the original structure is visible at left. The entire superstructure of the Duffins Creek Bridge was replaced when Hwy 401 was widened in this area in 1997. See an Enlarged Photo Here. Photo taken on November 9, 1995.

In the foreground, Toronto-bound traffic heads east into the city via Hwy 401, while Mississauga Road carries suburban traffic into Streetsville. At one time, the Mississauga Road Interchange was the only interchange situated along Hwy 401 between Trafalgar Road and Hwy 10 (Hurontario Street) - and for good reason. When Hwy 401 was first built in this area in the late 1950s, Streetsville was a small rural village located many miles out of the city. Suburban development in the 1970s and 1980s transformed Streetsville into a large employment and residential district. See an Enlarged Photo Here. Photo taken in September 1996.

Left - Eastern side of the Neilson Road Overpass on Hwy 401 in Toronto. The bridge-mounted pull-through sign for the westbound Hwy 401 Collector Lanes still bears a reference to Markham Road as Hwy 48. Although signed along Hwy 401 until recent decades, Hwy 48 through Metro Toronto had actually been under municipal jurisdiction since 1963. However, the route of Hwy 48 was signed along Hwy 401 to aid in way-finding, much like Metro Toronto's other non-freeway King's Highways which were generally under municipal jurisdiction. Other than provincial freeways, Hwy 27 was the only King's Highway retained by the province within Metro Toronto by the 1990s. All other signed highway routes within Metro Toronto were actually just municipal streets. See an Enlarged Photo Here. Photo taken on May 29, 1997.

Careful observers will note that the westbound Hwy 401 Collector Lanes once had four through lanes immediately west of this structure, as opposed to the current three lanes. When the Express-to-Collector Transfer at Allen Road was reversed to become a Collector-to-Express Transfer in the early 2000s, it removed the need for an additional "away" lane downstream of the transfer point. The reversal of this westbound transfer point at Allen Road was carried out as part of a broad highway rehabilitation project between Bathurst Street and Jane Street under Contract #2000-0036. This change greatly improved traffic operations along Hwy 401 in this area, by providing a better traffic balance in the Express-Collector Lane System west of Allen Road. See an Enlarged Photo Here.

Until Hwy 401 was reconstructed through this part of Toronto in the 1960s, Martin Grove Road did not pass below Hwy 401. Rather, Martin Grove Road came to an end at a pair of T-intersections with Dixon Road on either side of Hwy 401. Under Contract #1966-296, the Dixon Road Interchange was rebuilt. In doing so, engineers also designed this direct connection below Hwy 401 between the discontinuous north and south legs of Martin Grove Road, so that it formed a single continuous street.

Right - Eastern side of the expanded Pickering CNR Subway on Hwy 401 in 1998, after the completion of the new Express-Collector Lane System through Pickering. The original structure was retained and two additional spans were built at the north and south end of the existing structure in 1996. The new span over the eastbound Collector Lanes is a Warren-type steel through truss structure. See an Enlarged Photo Here. Photo taken on September 25, 1998.
