Project Details

This project involved the rehabilitation of Blair County Bridges 1, 2, and 3 located in the City of Altoona and Logan Township. The bridges are the main route between 4th Avenue in the Juniata Section of Altoona and Route 764 in Logan Township.

Keller Engineers, Inc. completed the rehabilitation project within an accelerated schedule that was set to minimize the bridge closing impact to the surrounding community and school bus traffic.

The project was undertaken to repair and extend the life of the three bridges. It included replacement of the existing bituminous deck wearing surfaces with new reinforced concrete decks, repair of the concrete bridge barriers, repair of the existing prestressed concrete bridge beams, and associated guiderail and roadway approach work.


For over 20 years I have had the privilege of working with Keller Engineers and their staff of surveyors, and civil and structural engineers on over $150 million worth of work. During these project relationships and partnering opportunities, my architectural teams have received nothing but premium professional services and courtesy towards my own staff, clients and prospective clients with stellar attention given to building and site details, client responsiveness and peer respect. I look forward to many more teaming opportunities and urge any other architectural firms, municipalities or clients who have not worked with Keller Engineers to do so. You will be pleasantly surprised! Richard L. Karcher, AIA, NCARB
