The weather forecast has caused PennDOT to reschedule its weekend closure for the Route 20 (Ridge Road) bridge in Girard Township, Erie County.

The bridge will now be closed from 8 p.m. Friday, Sept. 20, to 6 a.m. Monday, Sept. 23.

The closure will allow crews to pave the new concrete deck on the structure, which cannot be done under rainy conditions.

A detour using Route 18, Interstate 90, and Route 98 will be posted.

When the closure is lifted, traffic will be reduced to one lane controlled by a temporary traffic signal for seven days.
