PITTSBURGH, PA (October 11, 2020) The Greenfield Bridge, which had been closed for maintenance, reopened this weekend ahead of schedule.
The City of Pittsburgh’s Department of Mobility and Infrastructure (DOMI) implemented a closure September 21 that was supposed to last 30 days.
Mosites Construction Company, the contractor who built the bridge, addressed several outstanding issues to ensure the longevity of the structure. The concrete deck surface was milled and overlaid with a 1-1/4” thick concrete surface meant to ensure water does not permeate into the deck. Also, the protective coating on the east bridge barrier was replaced to address flaking and peeling that had been observed.
