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.


Penn Cambria School District has collaborated the last 4 years with the Keller Engineer’s team to complete a multi-phased paving and drainage project on our HS campus. I have personally worked with Adam Long, Brian Smith and Shawn Ritchey throughout the entire project and they made Penn Cambria feel like we were their only client. The personal attention to our needs and specific details of this project were second to none. The communication aspect of the Keller Engineer Team was outstanding. We trust their process, their design and their commitment to a quality project that when completed, we are all very proud of. Bill Marshall, Superintendent Penn Cambria School District
