The project, in cooperation with the Federal Highway Administration (FHWA), involves the reconstruction of two full interchanges: Exit 53, the Yukon Interchange provides access to and from Huntingdon Street and S.R. 3010 (Wyano Road); and Exit 54, the Madison Interchange provides access to and from S.R. 3037 (Waltz Mill Road) and S.R. 3014 (Borough Line Road/Hunker Waltz Mill Road).
Deficiencies in roadway geometry, spacing of the interchanges, and condition of the structures coupled with increasing volumes have decreased safety in operations. This transportation project will address the roadway and structural deficiencies and accommodate the projected traffic demand thus benefiting the local community. The overall project includes reconstruction of 3.7 miles of S.R. 0070, widening the median to a minimum of 10 feet, providing 12 foot outside shoulders, reconstructing the interchanges at Exits 53 and 54 by lengthening the ramp acceleration and deceleration lanes, and providing an eastbound auxiliary lane between the two interchanges. The project also includes replacement of four mainline S.R. 0070 bridges, one mainline S.R. 0070 buried culvert, a new proposed culvert at the eastbound on- and off-ramps for the Yukon Interchange and maintenance on one S.R. 3010 structure.
Construction work continues through the winter as weather permits to install drainage, electrical conduit, excavate and build embankments along the eastbound side, and construct the new on and off ramps at Yukon. Once weather permits, construction of the new westbound lanes will resume, as well as completing the westbound portion of the new bridges, resuming work around the Madison interchange, and other work throughout the project.
Motorists travelling Interstate 70 between Exits 51 and 57 can expect traffic shifts to allow for ongoing work to construct the new concrete roadway. Short term single lane closures are also possible. The Ramps at Yukon remain closed during construction of the new concrete pavement which will be completed as soon as weather permits.
