Traffic is about to get a little crazy in Haverford.

On Nov. 29, PennDOT will begin a $5.2 million project to replace the structurally-deficient, 85-year-old College Avenue bridge over SEPTA railroad tracks and adjacent culvert over Cobbs Creek.

Motorists will need to follow Cooperstown Rd., Ardmore Ave. and Haverford Ave. to detour around the bridge closure.
