The Pennsylvania Department of Transportation says it has closed the Loux Covered Bridge In Bucks County because an oversize truck damaged it. Bridge engineers are developing a plan to repair or replace damaged wooden components, and it will probably stay closed for about a month.  The bridge has an eleven-foot height limit and it spans Cabin Run on Pipersville-Wismer Road, on the border between Bedminster and Plumstead Townships.  It’s on the National Register of Historic Places.
