Project Details

This project included removing failing and collapsed stone masonry retaining walls and construction of new retaining walls to support a two-block section of the southern lane of Pennsylvania Avenue.  In their place, galvanized steel walls with reinforced concrete facing were designed and constructed.  The walls, located between Franklin and Jefferson Streets, total more than 1,000’ long and have a maximum height of 10’.

To match the context of the Mount Union Historic District and the adjacent East Broad Top Railroad National Historic Landmark, the walls include concrete form liners, were stained to match the appearance of the original walls and display a black coated traffic barrier which aesthetically blends with the railroad and neighborhood setting.

We have teamed with Keller Engineers on several design-build projects for PennDOT. When selecting a designer, the more critical factors are trust and competence, more so than a low price. If your designer makes a mistake in quantities it can cost you a lot of money. We have stayed with Keller Engineers because we trust them to provide competent service at a competitive price.  S.
