PennDOT Upgrades Demonstrate Sustainability

摘要

The Pennsylvania Dept. of Transportation (PennDOT), District r r, is investing $95 million in improvements to a portion of State Road 28. Pittsburgh residents have travelled this passage since the early 1800s, when the corridor supported a wooden plank road, a canal, a Belgian block street, streetcar traffic, railroads, trails and the paved state road. Five construction contracts will provide system upgrades improving capacity, safety and geometry. Completion is slated for 2014.
