Unified Traffic Plan – Phase I
Lexington Town Council approved the Unified Traffic Improvement Plan in April 2005 and spent the last eight years aggressively pursuing funding for the project. Phase I of this project is underway, supported by $14.5 million through state and federal funding. The plan was developed by SCDOT engineers and has been modeled to provide the most efficient and cost effective solution to the ongoing traffic issue faced by the Town of Lexington.
The Unified Traffic Plan utilizes the existing road network to improve traffic conditions and safety, while limiting impacts to social, cultural and natural resources.
As the Town of Lexington continues to experience unprecedented growth, roadway expansion and improvements are imperative to help the area continue as an economic engine for our state.
Phase I includes intersection improvements along Columbia Ave.: Widen Columbia Ave. from Reed Ave. and West Butler St. to Park Road and add dedicated right turn lanes on Park Rd. and West Main St. Sidewalks are also included in this project.
*SCDOT will be performing most of the construction during off peak hours of 7pm-7am to relieve traffic congestion although some work will be necessary to be performed during the daytime hours.*
Phase I of the Unified Traffic Plan is expected to be complete in Spring 2014.

Adaptive Computerized Signalization System
- Currently in the design phase. The project has been divided into two phases.
- Phase-1 will include 19 of the 35 signal locations and is planned to bid November 10, 2014.
- Phase-1 anticipated Notice to proceed will be approximately February 1, 2015.
- Phase-1 construction should last approximately 9-10 months.
- Phase-1 system is expected to be fully operational by the end of 2015.
Operations and Benefits
- Detects the approaching and standing vehicle using cameras
- Adapts to local traffic demand using digital technology
- Develops the most efficient way to move traffic using a "greedy" algorithm.
- Constantly measures the volume
- Focuses on minimizing the delay or wait time
- Serves minor streets during "gaps" in major streets
- Optimizes the traffic corridor to experience as few stops as possible
- Coordinates with signals downstream the volume of traffic in queue
- Considers the amount of travel time needed between signals
- Creates "green tunnels"
- Serves minor streets during gaps on major street traffic
- Serves left turns (only when needed) at beginning or end of the green tunnel

- Improves travel time
- Reduces accidents
- Reduces fuel consumption and emissions
- Eliminates constraints on current signal operations and timing
- Operates signal "intelligently"

Corley Mill Intersection
SCDOT Construction on Sunset Blvd at Corley Mill and Ginny Lane Intersection
Road construction has begun at the Sunset Blvd. (HWY 378), Corley Mill Rd. and Ginny Ln. intersection. The work will consist of adding new pavement on Sunset Blvd. before Ginny Ln. The addition of this pavement will allow for a new configuration at the intersection and a new traffic signal will also be added.
Additional work that will be performed includes concrete, milling, paving and striping. The traveling public is asked to adhere to all posted signs and follow traffic control as the construction is being done as additional lanes will be created during the construction process.
The project is in conjunction with the opening of River Bluff High School and is anticipated to take six week. It is also in advance to the future Corley Mill Rd. Improvement Project slated to be complete in September 2014.
Road work will be conducted during the non-peak time frame from 7pm-7am but there will be activity off the pavement during the day.
