Update - Temporary Lane Closure 16th Avenue Between Ninth Line and Highway 48/Markham Road

The Regional Municipality of York is working in your community rehabilitating a 1.5 km section of the York Durham Sewage System that runs on 16th Avenue from Mingay Avenue to west of Williamson Road. The work involves installing a temporary sewage bypass pipe, rehabilitating two access shafts, relining the trunk sewer, and other work.
 
The sewage bypass pipe is being installed underneath the Metrolinx railway crossing, located just east of Highway 48/Markham Road on 16th Avenue. For safety at the railway crossing, the westbound traffic cannot be diverted into the eastbound lanes. As a result, the westbound lanes of 16th Avenue between Ninth Line and Highway 48/Markham Road will be temporarily closed nightly, from Sunday to Thursday, between 9 p.m. and 5:30 a.m. The road will be open to local traffic and emergency services only. The lane closures will only affect westbound traffic travelling from Ninth Line to Highway 48/ Markham Road. During all other times, three lanes of traffic, one westbound and two eastbound, will be open between Highway 48 / Markham Road and Ninth Line.

Temporary Lane Closure: In the evening, beginning August 15 to October 31, 2022, from Sunday to Thursday between 9 p.m. and 5:30 a.m.
