I-83 South Bridge Project


Project Description

The I-83 John Harris Memorial (South) Bridge was built in 1960, and widened in 1982, and connects downtown Harrisburg to its neighboring communities to the west in Cumberland County. The bridge currently carries more than 125,000 vehicles over the Susquehanna River every day.

The South Bridge is nearing the end of its serviceable lifespan, which means that wear and tear requires more regular, frequent, and costly repairs. In addition to the replacement of the bridge, the Lemoyne interchange will be reconfigured, the S. 3rd Street bridge in Lemoyne will be replaced, and the viaduct from the Susquehanna River to Cameron Street including the Front Street/2nd Street interchange will be reconstructed. The purpose of the I-83 South Bridge Project is to improve traffic flow and safety around the Harrisburg metro region. 

The comment period for the Environmental Assessment ended on November 16, 2023. Responses to comments will be prepared and included in the NEPA decision document, which will be posted on the project website in early 2024. You can view the EA on our previous virtual public meeting here.
