Airport Access Road, Design-Build
The Pennsylvania Department of Transportation, District 10-0 contracted for the construction of a new diamond interchange at the existing overpass of Township Road T-544 over Interstate 80 in Jefferson County. The bridge portion of the project was the first modified turnkey (design build) project in PennDOT District 10-0. Kimball teamed with contractor Glenn O. Hawbaker, Inc. to complete this project.
Solution: Kimball modified the preliminary bridge design drawings prepared by others, for State Route 6830, Section 590, in Jefferson County, Washington Township at the I-80 and T-544 (Sensor Road) Intersection. Instead of the proposed four-span bridge with stub abutments, Kimball designed a two-span bridge with MSE abutments. Kimball eliminated two spans and reduced the construction cost of the project. The project was completed on time and within budget.
Result: The new 4-mile, direct access route from Interstate 80 to the Dubois/Jefferson County Airport will contribute to increased commerce at the airport facility and the greater Dubois area. Prior to this project, motorists travelling to the airport from I-80 were forced to use one of two exits that were 19 miles apart, and travel on two-lane State Route 830 for 10 miles or more.
Described as an economic lifeline, the Pennsylvania Department of Transportation’s Route 830 Airport Access Project in Jefferson County, PA, was selected as one of the top 10 national finalists for “America’s Transportation Award,” following a regional win. The competition was sponsored by AAA, the U.S. Chamber of Commerce, and the American Association of State Highway and Transportation Officials (AASHTO) to recognize significant state department of transportation projects.
