U.S. ROUTE 17 ACE BASIN WIDENING PROJECT
Location: Colleton & Beaufort Counties, South Carolina
Completion Date: May 2011
Phillips & Jordan Role: Prime Contractor
U.S. Route 17 is a part of the National Highway System and the Strategic Highway Network for Defense Preparedness. Originally constructed in 1926, U.S. Route 17 extends for 1,189 miles along the southeastern coast of the United States from Virginia to Florida. In the State of South Carolina, U.S. Route 17 provides a direct route between the coastal cities of Myrtle Beach, Charleston, and Beaufort. Of the 211 miles of the highway in the State of South Carolina, 173 had been previously upgraded to a 4-lane roadway.
Phillips & Jordan was contracted under a design-build arrangement to transform an 8 mile section of the highway from Gardens Corner to the Combahee River Bridge from a 2-lane two-way traffic configuration to a 4-lane two-way median separated design. One challenging aspect of the project was the construction of 7,000 linear feet of roadway over an existing tidal marsh. The closure of the existing roadway was not allowed and further encumbering the construction was a nesting pair of bald eagles that limited access and noise levels in the area. To mitigate these issues, Phillips & Jordan devised and implemented a geotechnical plan that required the use of several types of geosynthetic materials, thousands of wick drains, and a strict embankment placement plan based on pore pressures and settlement monitoring.
