HWY 401 #1283             HWY 401 #1284

Left - Sheppard Avenue Extension Overpass (today's Port Union Road) on Hwy 401 in Toronto. In 1971-1972, the original 1947 interchange at the Lansing Cut-Off (today's Port Union Road) and the adjacent Hwy 2A & Kingston Road Interchange were both replaced by a new consolidated interchange with improved geometry. The replacement of the 1940s and 1950s-era interchanges coincided with the widening of Hwy 401 from 4 to 6 lanes approaching the Rouge River. The new Sheppard Avenue Extension Overpass was designed to allow for the future construction of an Express-Collector Lane System on Hwy 401 below the structure. The eastern extension of the Hwy 401 Express-Collector System into Durham Region took place in the mid-1990s. See an Enlarged Photo Here. Photo taken on October 7, 1975.

NEW Right - The traffic signals at the south ramp terminal at the Brock Road Interchange on Hwy 401 are an odd combination of both yellow and green target backboards. Although green target backboards were commonly-used for Ontario's traffic signals during the 1970s, it is very unusual to see them used in combination with a yellow target backboard within the same intersection and on the same approach. What is especially perplexing is that these traffic signals were not a retrofit situation - they were brand new at the time this photo was taken. See an Enlarged Photo Here. Photo taken on October 9, 1975.

This structure carries traffic from the Southbound Don Valley Parkway (today's Hwy 404) to the Eastbound Hwy 401 Collector Lanes. The Southbound through lanes on the Don Valley Parkway are carried by Structure #2, which can be seen at left. Note the pre-Metric 20 m.p.h. advisory speed sign at right. See an Enlarged Photo Here.

Right - Don Valley Parkway, facing south from the Hwy 401 Interchange in Toronto in 1975. The absolute absence of traffic on the highway may come as a surprise to anyone who is familiar with this congested interchange today. At right, a single car can be seen entering the Northbound Don Valley Parkway (today's Hwy 404) from Eastbound Hwy 401. At the time this photo was taken, Hwy 404 didn't exist yet. The Don Valley Parkway ended about 1/2 mile to the north at Sheppard Avenue, after which the expressway ended and turned into a rural two-lane road (Woodbine Avenue). In 1977, Hwy 404 was completed and opened to traffic up to Steeles Avenue, bringing with it the promise of new development opportunities and prosperity for the many then-sleepy rural towns and communities of York Region.

This stylish illumination system was used on many Metro Toronto expressways up until the 1980s and 1990s, when they were phased out and replaced by a high-pressure sodium illumination system. Today, the Hwy 404 & Don Valley Parkway Interchange on Hwy 401 is illuminated using high-mast luminaires. Photo taken on December 11, 1975.

HWY 401 #1269

Above - Facing east towards Structure #5 at the Hwy 404 & Don Valley Parkway Interchange in Toronto in 1976. A subcollector lane was added below this structure in 1999 in order to separate longer-distance traffic heading north towards Newmarket on Hwy 404 from local traffic heading to the adjacent Sheppard Avenue Interchange on Hwy 404. The subcollector lane was added by excavating the embankment at right and constructing a retaining wall system. Prior to 1999, the proximity of the Sheppard Avenue Interchange on Hwy 404 created severe weaving problems between the exit ramp and the Hwy 404 & Don Valley Parkway Interchange. Traffic entering Northbound Hwy 404 from Eastbound Hwy 401 was forced to slow down while local traffic wishing to exit at Sheppard Avenue attempted to change lanes within the constrained amount of space between the two interchanges. Photo taken on April 5, 1976.

Left - Facing west along Hwy 401 towards the Bloor Street & Harmony Road Interchange in Oshawa in 1977, before reconstruction and widening. The section of Hwy 401 through Oshawa was widened from 4 to 6 lanes during a multi-year reconstruction project that took place between 1978 and 1980. In addition to the highway widening, the depressed grass median was filled in and replaced by a concrete median barrier with paved inner shoulders. The reconstruction project also included the installation of a full highway illumination system, noise attenuation barriers and overhead guide signs. See an Enlarged Photo Here. Photo taken on August 30, 1977.

Left - Birchmount Road Underpass on Hwy 401 in Toronto in 1977, before reconstruction. Shortly after this photo was taken, Birchmount Road was rebuilt under Hwy 401 to accommodate the construction of a new grade separation over the adjacent Canadian Pacific Railway. The original alignment of Birchmount Road seen here was buried underneath a large earth fill, as a result of the grade-raise. Note the "angled" advance overhead guide sign on Hwy 401 for the Kennedy Road Interchange. Photo taken on September 30, 1977.

Even Hwy 400 South (today's Black Creek Drive) was accessible from the Express Lanes. Photo taken on October 14, 1977.

HWY 401 #1295

Above - Facing west along Hwy 401 towards Milton from Derry Road in Mississauga in 1979. This location marked the end of the first Hwy 401 widening contract west of Hwy 10 (Hurontario Street). Between 1977 and 1982, there were several widening contracts which took place along Hwy 401 between the Hwy 10 Interchange in Mississauga and the Hwy 25 Interchange in Milton. The start of the second widening contract, from Derry Road to Trafalgar Road, can be seen in the background of this photo. As part of these widening projects, a new concrete median barrier was constructed and the highway was widened from 4 to 6 lanes. The New Jersey median barrier made its debut in Ontario during the first Hwy 401 widening contract in 1977. This new concrete barrier type can be seen in the foreground. The New Jersey median barrier was utilized on many other freeway sections in Ontario during the 1970s and 1980s, effectively eliminating the need for higher-maintenance steel beam guide rail median types that were used on older Ontario freeways. See an Enlarged Photo Here. Photo taken in July, 1979.

HWY 401 #1296

Above - Derry Road Underpass on Hwy 401 in Mississauga in 1979. When this underpass was originally constructed in 1958, there was a separate eastbound and westbound structure. However, when Hwy 401 was widened from 4 to 6 lanes in 1977-1978, the two separate structures were joined together in order to accommodate the widened highway. In 1996-1997, Derry Road was widened to four lanes below Hwy 401, and the original underpass structure was replaced entirely. Photo taken in July, 1979.
