PennDOT is updating drivers on progress for a Route 522 improvement project in Lewistown, Derry, and Decatur townships in Mifflin County. Crews will focus on tie-in work today and tomorrow to smooth driveway and side road connections, with additional work on shoulders and concrete steps. This week’s plans also include placing topsoil and adjusting guide rails. Traffic flaggers will be on site, and drivers are urged to stay alert and follow speed limits. The $6.2 million project is set to wrap up by mid-November, depending on weather.
