View Project History & Funding
The I-78 Lenhartsville Bridge was built in 1955 and was last rehabilitated in 1985. This bridge is in a rural setting and crosses Maiden Creek in Greenwich Township, Berks County. It also serves as an overpass to PA-143. The bridge carries about 50,000 vehicles daily, approximately 30 percent of which is truck traffic.
The purpose of the I-78 Lenhartsville Bridge Replacement Project is to replace the existing bridge over Maiden Creek and PA-143 and widen it to accommodate the addition of auxiliary lanes and full inside and outside shoulders on I-78 in each direction. These modifications will provide a consistent typical section along the I-78 corridor.
The project is intended to address the substandard I-78 westbound deceleration and I-78 eastbound acceleration lane lengths to and from the PA-143 interchange.
