PennDOT Secretary Allen Biehler joined federal, state and local officials on March 14 to break ground for the $60-million Traffic Route 15 improvements along Steam Valley Mountain in northern Lycoming County.
Secretary Biehler noted that the project is one of the four largest contracts planned by PennDOT this year and is the largest single contract in the history of Engineering District 3. The improvements under this project will take place within a 10-mile stretch of Traffic Route 15 between Trout Run and Buttonwood.
The three-year project will include replacing or rebuilding approximately 5.5 miles of southbound lanes and 3 miles of northbound lanes. It will have a full interchange with Traffic Route 184 and a split-diamond interchange with a connector road between Steam Valley and Green Mountain Roads farther south. Portions of the northbound lanes will be resurfaced.
In the first year of construction, work will focus on the northbound lanes, ramps and structures, and the construction of the Traffic Route 184 interchange bridge. Northbound and southbound traffic will be carried by the southbound lanes between Traffic Routes 184 and 284.
In the spring of 2009, both northbound and southbound traffic will be carried by the northbound lanes between Traffic Routes 14 and 184 until late 2010. This will allow construction of the new southbound lanes and ramps over the final two years of the project. Trumbull Corporation of West Mifflin is the primary contractor. The project was designed by Gannett Fleming, Inc., Camp Hill. Overall project completion is planned in late 2010.
