Preliminary Design began in 2011 on the future reconstruction and widening of the Northeastern Extension of the Pennsylvania Turnpike (I-476) north of the Lansdale Interchange to north of Clump Road between milepost A31 and A38. The seven-mile project corridor traverses Lower Salford, Franconia and Salford Townships in Montgomery County.
The project team has been developing base
mapping and conducting field work to assess existing traffic,
environmental, and subsurface conditions. These
investigations are required to progress with final design of the
overhead bridges and the preliminary design of the mainline
widening and reconstruction. The overhead bridges along the
project corridor are only wide enough to accommodate the current
roadway width, so they will need to be replaced before the
mainline widening can occur. Construction on the overhead
bridges is expected to begin in the spring of 2013 and
construction on the mainline is expected to begin in 2017.
An Open House Plans Display was held on April 11, 2013 to introduce the Preliminary Design Plans to the Public. For additional information on this project, please click on the appropriate button in the menu at left.
