Construction on one of the most frustrating routes to drive in Calgary is almost complete.

For nearly three years, rotating lane closures and bumper-to-bumper traffic has been the norm for drivers who use Glenmore Trail.

Construction on the causeway between Crowchild Trail and 14 Street, S.W., started in 2005.

The upgrades cost nearly $170-million and include a new pedestrian bridge and additional lanes.

But things will get a lot worse before they get better.

Between now and September 17th, major delays can be expected along Glenmore Trail.

From 7 p.m. Wednesday until 6 a.m. Thursday, eastbound Glenmore will be completely closed at 14 Street. Traffic will be detoured while paving crews are at work.

From 10 p.m. Wednesday until 5 a.m. Thursday, westbound Glenmore will be reduced to one lane between 14 Street and Crowchild Trail for paving.

The entire Glenmore causeway upgrade is expected to be completed in early October.
