Forty-six state-owned bridges in the Pennsylvania Department of Transportation District 11-0's three-county area will be posted soon with new or lowered weight restrictions to slow the rate of deterioration of those bridges and to ensure safety.
Those structures are among approximately 1,000 structurally deficient bridges statewide that PennDOT Secretary Barry J. Schoch authorized for new or added weight restrictions on Aug. 22.
The restrictions will also apply on 29 county or locally owned bridges in the District 11 area of Allegheny, Beaver and Lawrence counties.
Among the list of state-owned bridges in the three-county region that will have weight restrictions posted on them in coming weeks is one in Baldwin Borough on Streets Run Road.
The list includes combination loads, primarily tractor-trailers, which have higher weight limits because of how their weight is distributed.
The Streets Run Road bridge, which goes over the Streets Run creek, is found near the four-way intersection of Streets Run, East Willock and Doyle roads. That bridge's new weight limit is 32 tons, except for combinations, which can go up to 40 tons there.
A popular bridge for some Baldwin residents that also has a new weight restriction is the Liberty Bridge in Pittsburgh (over the Monongahela River). That bridge's new weight limit is 30 tons (40 for combinations).
PennDOT is taking this step because legislative inaction on transportation funding left uncertain the department's ability to repair or replace these bridges, according to a news release. The lower weight limits will help to extend the service life of these deteriorating structures.
