Starting Tuesday, June 22, TTC crews are replacing rail on the streetcar right-of-way for both east- and westbound stops

• on King Street West at Spencer Avenue.

By 7 a.m. June 22, crews set up work zones near both stops. Crews work only in the track area to:

• saw-cut, mill and break concrete to expose the rail;
• replace old rail with new rail; and
• place new concrete.

The TTC says, “While most work typically ends at 11 p.m., rail work of this nature requires periods of around-the-clock work to ensure quality installation of new rail and concrete.”

When crews replace the old rail with new rail, they also cut, weld and grind the new rail. They’ll pour concrete in the track area and set it to cure. The new concrete requires curing time before the crews can remove the work zone and traffic can again flow over the entire roadway.

The work zones restrict traffic to the curb lanes. The City of Toronto is temporarily prohibiting on-street parking in the area to maintain traffic flow. The work zones may also block motorists from turning left onto or off of King West.

Ongoing construction at the intersection of Queen Street West / King Street West / The Queensway / Roncesvalles Avenue has required the TTC to replace streetcars along various routes with buses through the area. Passengers aboard buses along these routes can expect delays:

• 301 Queen overnight;
• 304 King overnight;
• 501L Queen / Long Branch;
• 501P Queen / Park Lawn; and
• 504Q King.

Track-replacement at King West / Spencer and the resulting TTC service changes continue until June 28 (4:30 a.m.)
