(WPXI) PITTSBURGH — Pittsburgh Regional Transit began installing curb extensions at five major bus stops in Downtown Pittsburgh. They’re designed to align the bus stop with the parking lane, allowing buses to stop to pick up and drop off riders without weaving in and out of traffic. PRT said this will give riders more visibility in a protected waiting area and make boarding buses safer and easier, mostly for riders who use mobility devices such as canes, walkers or wheelchairs. The Downtown Pittsburgh locations receiving these upgrades are: Forbes Avenue at Grant Street, Wood Street at Sixth Avenue, Penn Avenue and Stanwix Street, Fort Duquesne Boulevard at Sixth Street and Wood Street at Forbes Avenue which is temporarily on hold due to a non-PRT related project. Installation is scheduled to take place between 9 a.m. to 3:30 p.m. Monday through Friday, with each platform taking up to three days to complete. The entire project, which also includes updates to pavement markings and street signage, is expected to take three weeks. The total cost of the project is projected to be around $800,000.
