PennDOT plans Tower Road bridge replacement in Limestone Township

Commuters, farm traffic, school buses and delivery vehicles that rely on Tower Road in Limestone Township will hit a full closure beginning June 10, when PennDOT shuts the road between Turkey Run Road and Brouse Road for a bridge replacement over Turkey Run. Crews are scheduled to start mobilizing equipment on June 8, and the project is expected to run through August, weather permitting, with a detour posted along Route 304 and Ridge Road.

PennDOT says the crossing carries an average of 209 vehicles a day, a reminder that the bridge is lightly traveled by state standards but still important to the people who use it as a local connector. During the closure, buses and emergency vehicles will have access, which should help preserve school transportation and first-response coverage even as regular traffic is rerouted around the work zone.

The project will remove the existing bridge and replace it with a new box culvert over Turkey Run. PennDOT says the bridge was built in 1930 and rehabilitated in 1975, making this a long-awaited overhaul of a structure that has already served the township for generations. The work includes excavation, removal of the existing bridge, installation of the new box culvert, backfill, approach work, paving and line painting, all handled by department forces.

In Union County, the Tower Road job fits into a wider push to address aging local bridges before they fail into a more disruptive emergency. In 2024, county officials said nearly $2.2 million in Multimodal Transportation Fund support had been secured to replace six locally owned bridges in poor condition, with PennDOT Secretary Mike Carroll highlighting that effort in New Berlin. That broader investment has made bridge work a recurring feature of the county’s infrastructure agenda, from township roads like Tower Road to other local crossings that keep rural travel moving.

Drivers who use the Limestone Township corridor should plan ahead for the detour, expect added travel time on Route 304 and Ridge Road, and watch for changing conditions as the closure takes hold next month. PennDOT says 511PA will carry real-time travel information, including delay warnings, weather forecasts, traffic speeds and camera views, as the replacement moves toward its August completion.
