A wooden bridge spanning the Pilot Butte Creek in east Regina is not strong enough to take heavy truck traffic, according to city officials, forcing detours until a fix is made.

The structure, on Victoria Avenue East at Coleman Crescent, is over 50 years old.

Detours were set up on Tuesday affecting heavy truck traffic.

The city said the restrictions, based on weight, will remain in affect until the bridge can be strengthened or rebuilt. It was not known how long that would take.

Despite the detour signs, large semis were still seen using the bridge on Thursday.

About two kilometres before the bridge, truckers are directed to Highway 46, and then to McDonald Street.
