PennDOT has announced a busy schedule of maintenance activities in Mifflin County, all set to kick off beginning today. Much of it has to do with bridge maintenance. According to PennDOT, Pennsylvania has some of the oldest bridges in the country, and the preventive maintenance is vital in extending the life of those structures. Drivers are urged to exercise caution in the work zones to ensure the safety of maintenance staff. The work schedule is subject to change due to weather conditions, emergencies, or other unforeseen interruptions.
