Concrete patchwork will start July 14 on the northbound and southbound lanes of Interstate 99, according to the Pennsylvania Department of Transportation (PennDOT). Work will be between Exit 1 (Bedford/PA Turnpike) and Exit 3 (Johnstown/Cessna) in Bedford County. Traffic will be reduced to a single lane in the work zones. This is the next phase of a larger project in work zones in Bedford and Blair Counties.
