Project Details

The project consisted of a superstructure replacement and widening of the bridge having three 57’-0” spans. The existing steel superstructure was removed and replaced with new steel I-beams and a concrete deck. The deck and all substructure units were widened to accommodate two traffic lanes. Total project length was 630’-0” including approach roadway and drainage facilities.

The bridge is located directly adjacent a church. Care was taken to minimize impact to the church and associated parking facilities. Additionally, the project included several environmental concerns. Stream disturbance was minimized to avoid impact to a species of concern.


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
