If you want to take one last drive across the 93-year-old Greenfield Bridge, you had better do it before Friday at 10 p.m.

That’s when the bridge will close to automobile traffic; it will remain closed until the new bridge opens in May 2017.

The Pittsburgh Department of Public Works will soon be outfitting 11 downtown intersections with brand new traffic lights, poles, wires and pedestrian signals.

Legislation to approve the upgrades is up for a final vote in City Council on Tuesday.

DPW Deputy Director Patrick Hasset said the new signals will also be connected via fiber optic cables to the DPW’s control room in City Hall, where they’ll be able to control the signals remotely. Currently, the department can remotely control about 130 the city’s more than 600 signals.
