US 17 ACE Basin Parkway

US 17 ACE Basin Parkway - Segment 2

Thanks to cooperation among local, state, and federal agencies, Segment 2 of the US 17 ACE Basin Parkway project has been completed and opened to traffic in Colleton County between South Carolina (SC) Route 64 in Jacksonboro, SC and Lightsey Plantation, just north of the Combahee River. This 14-mile segment of roadway was improved from a two lane highway with some passing lanes to a new four lane roadway with a divided median and portions of asphalt paved median.

The project was completed in October 2013, and included the replacement of the existing US Rotue 17 bridges over CSX Railroad, the Ashepoo River with new structures. Additionally, the intersection of SC Route 303 with US Route 17 was relocated and the intersection of SC Route 64 with US Route 17 was reconfigured and signalized. Both routes now intersect US Route 17 with a more traditional “T” type intersection configuration. Other improvements included enhanced drainage system, safer shoulders, and new guardrails.

With the completion of Segment 2, the full 21-mile corridor between US Rouet 21 at Gardens Courner to SC Route 64 in Jacksonboro has been improved to create a 4-lane facility.

This project improves the safety of this important highway, while preserving the natural, pristine beauty of South Carolina's valuable estuary where the Ashepoo, Combahee, and Edisto Rivers converge. The design/build contract cost for Segment 2 was delivered at $75 million.

US 17 ACE Basin Parkway Improvements Wrap Up For Segments 1 and 2A

Thanks to funding by FHWA, SCDOT, and Beaufort County with work by SCDOT and the US 17 ACE Basin Parkway Segment 1 and 2A Team improvements have been made to US 17 between Lightsey Plantation in Colleton County and Garden Corner (US 17/US 21) in Beaufort County. Almost ten miles of two lane roadway was improved to create four lanes, two northbound lanes and two southbound lanes, and a new Gardens Corner Interchange.

Additional improvements in this area include two new bridges and a wide naturally landscaped median between the Combahee River and Jacob White Road; a new turning lane and landscaped median between Jacob White Road and the old Piggly Wiggly; a new signalized intersection of US 17 with Jacob White Road and a realigned Big Estate Road; a multi-use path between Jacob White Road and the former Piggly Wiggly; an enhanced drainage system, safer shoulders, and new guardrails; and a revamped Gardens Corner Interchange with a US 17 overpass and traffic circle connecting US 17 southbound traffic to US 21.

The design/build contracts for these improvements delivered the project under-budget at $100.4 million dollars.
