This project consists of a 7.3-mile multi-lane widening, providing a safer, higher-capacity north-south route from Newport along the west side of Lake Wylie to just south of the SC Hwy 55/49/274 intersection. The improvements will widen SC Hwy 274 to a five-lane section, with curb and gutter and a center turn lane. CME provided environmental permitting and documentation, public involvement and education, design management, property acquisition, and construction administration services for this project.
Environmental Permitting
Construction impacts to jurisdictional stream channels and wetlands were permitted using Nationwide Permit #14 through the US Army Corps of Engineers Charleston District. A Federal Energy Regulatory Commission (FERC) Conveyance Permit for the construction of a second bridge across the Big Allison Creek arm of Lake Wylie was coordinated with, and approved by Duke Energy Lake Management.
Public Involvement and Education
Newspaper display advertisements, website updates, and signage along SC Hwy 274 were used to keep the public informed about construction activities.
Design Management
CME began providing design management services for the project during the right of way acquisition phase, and continued these services throughout the construction phase of the project. We coordinated all design activities with the acquisition efforts, performed design reviews for the final construction documents, and addressed design-related issues during construction. Additional surveying and right of way staking efforts for the project were coordinated by CME. We also managed the NPDES permit application process including reviewing and submitting the application, responding to comments, and completing the process to obtain the permit.
Property Acquisition
CME's services included the acquisition of 11 temporary drainage easements and one relocation for the road widening project.
Construction Administration
CME provided construction engineering and inspection services for this project. CME also prepared bid and contract award documents, coordinated utility relocation work and resolved construction issues with the design consultant as necessary during construction. The project included the construction of a 150-foot-long bridge over Little Allison Creek, a 320-foot-long bridge over Big Allison Creek, and the installation of more than 39,000 linear feet of concrete storm drain pipe and 270 drainage structures.
