MP312-319 Project Overview

Preliminary Design began in Spring 2012 on the future reconstruction and six-lane widening of the Pennsylvania Turnpike (I-76) between mileposts 312 and 319. The project  begins just west of the Downingtown Interchange (Milepost 312) and extends east to the Route 29 Interchange (Milepost 320). The seven-mile project corridor traverses Upper Uwchlan, Uwchlan,  West Pikeland, and Charlestown Townships in Chester County.

An Open House Plans Display was held in May 2014 to introduce the Preliminary Design Plans to the public. 

The project has been divided into two design and construction sections, both of which are currently in Final Design. The first section is from Milepost 311.60 to Milepost 316.19 and is currently being advanced. The second section is from Milepost 316.19 to Milepost 319.44 and will follow thereafter. Upon completion of these two Mainline projects, the existing four-lane facility will be upgraded to a six-lane facility (three 12-foot travel lanes westbound and three eastbound) with 12-foot inside and outside shoulders. Construction dates for both sections have yet to be determined. Between 2010 and 2016, three overhead bridges (Bodine Road, Valley Hill Road (SR 1021) and Yellow Springs Road) were replaced within the project limits.
