Main Street Markham construction:
TTC detours start July 2



Update — Monday, September 16, 7:55 a.m.: Buses have resumed their regular routes along the street.


Update — Tuesday, July 23, 19:57 p.m.: Construction has now advanced further north along Main Street North to its intersection with Parkway Avenue and Bullock Drive. GO Transit is detouring buses operating along the 54 Markham / York U, 70 Uxbridge / Stouffville and 71 Stouffville / Toronto routes, starting today.


The City of Markham is closing:

  • Main Street North Markham, northbound lanes, between Robinson Street and Highway 7

during the second phase of a project to rebuild the roadway.

The TTC is detouring buses operating along the 102D Markham Rd route to accommodate the construction.


The City of Markham started to rebuild Main Street Markham from Highway 7 to Bullock Drive Sunday, July 1, 2012. The first phase of the project required the City to install the underground services — water mains, storm sewers and other services connections. The City finished this work in December, 2012.

Now the City is resuming work to finish the rest of the roadworks and streetscaping. During this phase, the City is:

  • fully rebuilding the roadway with parking lay-bys, extending the curbs to provide larger boulevards;
  • increasing boulevard areas to improve streetscaping;
  • more clearly defining driving lanes and parking areas, with some new turn lanes at Centre Street, Robinson Street, and Bullock Drive;
  • improving the boulevards by planting more trees, refurbishing the streetlights, adding benches and installing festival flag poles.
