The major component has been completed, but work continues on a project that will impact traffic on Arthur Drive in Ladner for at least another 10 days.
The city last week advised motorists once again they would need to find an alternate route for upcoming lane closures on the roadway, from Whitworth Crescent to 36th Avenue, due to the relining and rehabilitation of existing twin culverts along the Mason Canal at Arthur Drive.
The road closure was in effect until Monday, May 15, with the city suggesting a detour route down 46A Street via 45th or 36th avenues.
Engineering director Steven Lan told the Optimist Wednesday that while the primary box culvert installation work across Arthur Drive is completed, there will be remaining works over the next 10 days, including the installation of the culvert headwalls and final paving.
Drivers can expect single-lane alternating traffic through the work zone to allow the remaining work to be completed.
The existing infrastructure was at the end of its service life and in need of replacement, according to the engineering department, noting the twin circular culverts were to be replaced with a box culvert, which includes a baffle system to provide flexibility for managing water levels during the irrigation season.
The box culvert is to eliminate flow constraint along Mason Canal and improve drainage in the area. The project is to also improve the supply of irrigation water to west Ladner and facilitate future irrigation water supply to Westham Island.
