PennDOT I-83 Expansion SW Impacts/ Sewer Stormwater Separation

Background:

PennDOT is undertaking an Interstate 83 (I-83) Master Plan to widen and improve the interstate in the Harrisburg area. The I-83 East Shore Section 3 Project limits stretch from the Susquehanna River to 29th Street. The proposed improvements include widening the I 83 corridor to three mainline lanes in each direction with additional lanes providing access to upgraded interchanges via a collector-distributor system. The I-83 Expansion Project will be divided into 3 contracts and construction will occur over the next 10 years.

Project Purpose:

Construction of a 48” Storm sewer diversion pipe system to redirect stormwater flow from the CSO-048 combined sewer system to Paxton Creek with the PennDOT I-83 Expansion Project.

Project Summary:

The total project will result in Combined Sewer Overflow reduction with the diversion of stormwater from catchments SS-011, SS-012, and SS-013.

The project will be financed by a PENNVEST (1% APR loan).
