The new LRT traffic barriers, which had been causing long delays at 111th Street and 51st Avenue are now fixed, according to a senior city official.

Bob Boutilier, Edmonton's transportation general manager, said Wednesday commuters will have to wait only four or five minutes to go through the intersection, which is the normal time they can expect to wait at other major intersections in the city.

The problem began Monday, the first day rush-hour commuters had to contend with trains on the new LRT extension on 111th Street.

By Tuesday, commuters were waiting up to 30 minutes to get through the intersection.

The problem was caused by trains getting priority going through the intersection, Boutilier said.

During rush hour, trains were arriving at five-minute intervals, but if they arrived in different directions around the same time, drivers had to wait for both, losing their turns to cross the tracks.

"Definitely there will be some challenges from time-to-time when the LRT car comes through but no different that what we would find at other intersections where you have a pedestrian crossing or some other issue in the intersection," Boutilier said.

"So, I think we pretty much nailed down the issues during the rush hour."

Boutilier said traffic cameras will also be installed at the intersection, allowing operators in the city's traffic control centre to adjust the lights if a backup does occur.
