Construction delays precipitated by June's sinkhole on Rideau Street have prompted the City of Ottawa to shut down a busy stretch of the road to all vehicular traffic so crews scrambling to complete the light rail tunnel underneath can work around the clock.
The closure, from Sussex Drive to Dalhousie Street, will go into effect at 8 p.m. Wednesday and will remain in effect until the end of December, the city said. Buses will be re-routed, and taxis and deliveries will be forced to steer clear of the area.
