PennDOT is informing drivers of the potential for short-term delays today, from lane restrictions on U.S. 22 between the Gallitzin Exit at the Cambria County line and the U.S. 22 East / Route 764 North Exit at Cross Keys in Allegheny Township, in Blair County. The contractor will be installing overhead signs with temporary lane closures alternating between the passing lane and the travel lane on U.S. 22. PennDOT stresses extra caution being used while driving through work zones.
