Cost:

$72,000,000.00

The joint venture between PKF-Mark III, Inc. and Neshaminy Constructors, Inc. designed and constructed the critical Route 29 cut-and-cover tunnel.  Construction was accomplished by a combination of forces working on water and land. The joint venture self-performed the installation of the dramatic 2' by 4' concrete piling along the water's edge, the 3' thick base and support slabs, and all of the tunnel's lighting and ventilation.

PKF also was awarded and completed an independent contract to install a themed, landscaped park on top of the supported slab.
