Originally constructed circa 1921, inspection and analysis of the structure has indicated the bridge needs to be replaced.

The bridge location and architecture suggest a context sensitive design and coordination with PennDOT for I-376 traffic impacts. It is anticipated that pedestrian, cyclist and vehicular traffic will be rerouted for the full duration of the work.

The closure has been rescheduled for the weekend of December 9, beginning at 10:00 p.m., Friday and ending at 6:00 a.m., Monday the 12th. During this closure, Mosites and their team will finish tightening all the connections of the steel, install the deck pans over the highway, and perform miscellaneous activities.

October 21, 2016 - REPLACEMENT OF THE BEECHWOOD BOULEVARD (GREENFIELD) BRIDGE PARKWAY EAST CLOSURE

The replacement of the Beechwood Boulevard (Greenfield) Bridge is approaching another milestone in the progression of the project.  Last week the massive crane was delivered on 37 semi-trucks and assembled on site, dominating the landscape with its 200 ft. boom.  Also on site are the structural steel elements including the arches delivered in three sections.  Mosites and their team will begin assembling the southern sections of the steel arches over the next couple of weeks.  This work will not impede traffic flow on the Parkway East.  However, on Friday November 4, at 10 p.m., the Parkway East, both inbound and outbound, will be closed until 6:00 a.m, Monday, November 7, to accommodate the placement of the steel arches and decking over the Parkway.  If the weekend is successful, both steel arches will be in place by Monday morning.  Then on Friday November 18, at midnight the Parkway East will be closed again until 6:00 a.m. Monday, November 21, for the placement of the remaining steel elements.  Following this closure, Mosites and their team will finish tightening all the connections of the steel and perform miscellaneous activities, but without impacting Parkway traffic.

Vehicular Detour Maps

Pedestrian and Bicycle Alternative Routes Map

NOTE: Greenfield Bridge is closed to all vehicular, pedestrian and bicycle traffic. Please follow Detours and Alternative Route(s).

Transit Detours

Port Authority of Allegheny will implement bus detours for four (4) transit routes that will be impacted by the closure of the Greenfield Bridge. The detours will be implemented as a regular service change and be reflected in the transit route timetables. This will help transit buses remain on schedule and protect the reliability of the routes for public transit riders.

The impacted transit but detours will start September 6, 2015, six weeks ahead of the anticipated Greenfield Bridge closure. This advanced implementation of the transit detours is due to the Port Authority regular quarterly service change also starting on September 6, 2015. Transit Routes being detoured include: 52L Homeville Limited / 53L Homestead Park Limited / 58 Greenfield / 93 Lawrenceville-Oakland-Hazelwood. Read more . . .
