Some construction photos of Highway 406 in Ontario through Welland. Despite the 400-series designation, Highway 406 was initially built as a two lane at-grade highway through Welland, and is only now, decades after initial construction, being widened to four lanes.
Some photos:
Hwy 406 crossing over the Welland River and Old Welland Canal. It is interesting to note that despite being side by side, the Welland River and Old Canal have different water levels.
Northerly view towards the Merritt Road overpass. The Merritt Road overpass was constructed in 2011 in an advanced contract to expedite the twinning work.
Southerly view approaching Woodlawn Road. During construction, Highway 406 followed what will become the southbound on and off-ramps through the future interchange.
Southerly view between the twin Welland River bridges. The new bridge is at left.
The Merritt Road interchange was opened to traffic during 2013, two years in advance of the completion of the remainder of the highway.
One of the more noteworthy features of the 406 construction was the addition of a new three lane roundabout at East Main Street. This is the first three lane roundabout on a provincial highway in Ontario. (Though it is not the first three lane roundabout in Ontario -- that was constructed in K/W several years ago).
Overhead signage approaching the roundabout at East Main Street.
This view looks easterly along East Main Street towards the Main Street Tunnel. Highway 406 parallels the Welland Canal. Immediately east of the Highway 406 roundabout, East Main Street (Highway 7146) dives below the canal in the pictured tunnel.
Taken in January, 2015, this photo shows the southbound lanes of Highway 406 had just about been finished before construction was shut down over the winter.
The whole set of pictures (I took a lot), and larger versions of the photos are available here:
