EAST ROCHESTER -- Construction work on Route 65 will lead to the temporary closure this weekend of a prominent Beaver County bridge.



The East Rochester-Monaca Bridge will be closed from 6 p.m. Friday to 6 a.m. Monday, weather permitting, PennDOT said, to allow for work on Route 65 near the bridge.



All bridge traffic will be detoured.



Northbound traffic should take Pennsylvania Avenue to Ninth Street, cross the Rochester-Monaca Bridge, follow Rhode Island Avenue to the Rochester roundabout, turn right onto Brighton Avenue toward southbound Routes 65/51, take the ramp to southbound Route 65 and follow back to the East Rochester-Monaca Bridge.



Southbound traffic should take Route 65 northbound to the Routes 18/east 68 off-ramp toward Rochester, follow Brighton Avenue to the Rochester roundabout, follow the roundabout to Rhode Island Avenue (Route 18), turn right onto Rhode Island Avenue and follow across the Rochester-Monaca Bridge, turn left onto Pennsylvania Avenue, and follow Pennsylvania Avenue to the East Rochester-Monaca Bridge.



This will be the first of three weekend closures of the bridge.



This work is part of the $20.2 million roadway project, expected to conclude in mid-August 2017. It includes milling and resurfacing, concrete pavement patching, drainage and guardrail updates, ramp reconstruction, curb and sidewalk work, bridge and retaining wall preservation, sign structure maintenance and signal improvements.
