The Johnnie Dodds Boulevard Project in Mount Pleasant involves improving approximately three miles of U.S. Route 17 from just north of the Arthur J. Ravenel, Jr. Bridge to the south side of the I-526 interchange, including the associated frontage roads and side streets. This project is funded by the Transportation Half-Cent Sales Tax and is being managed by the Charleston County RoadWise Program.
On August 12, 2008, a preferred alternative design was presented to the Mount Pleasant Town Council. Click here to view the presentation. Upon requesting that design modifications be made at the Houston-Northcutt, Shelmore and Anna Knapp intersections, Mount Pleasant Town Council gave their unanimous support for the project. Subsequently, Charleston County Council unanimously supported the revised design on August 28, 2008, and the design consultants immediately began work on preliminary design and plans. The project is slated to be constructed using the Design-Build approach to expedite the improvements. Construction is expected to begin in the summer of 2009.
The following summarizes the improvements of the recommended project:
- The widening from two lanes to three lanes in each direction on Johnnie Dodds Boulevard including curbs, gutters and medians. Median width will vary from eight to 12 feet similar to that between Hungryneck Boulevard and the Isle of Palms Connector on US 17. Click here for rendering.
- The frontage roads will be widened to provide one lane in each direction with four-foot–wide, marked bike lanes, curbs, gutters and a sidewalk on the outer edge for pedestrian use.
- Construction of a standard, signalized intersection at Johnnie Dodds Boulevard and Houston Northcutt. Left turns from Magrath Darby will be eliminated and right turns only allowed. A left turn lane from Johnnie Dodds Boulevard to Magrath Darby will be constructed. Click here to view.
- Construction of a traditional at-grade intersection at Johnnie Dodds Boulevard and Shelmore, Dragoo, and Anna Knapp with auxiliary turn lanes where warranted by traffic analysis. Pedestrian crossing will be provided at one section of the Shelmore and Anna Knapp intersections to allow for safe crossing on Johnnie Dodds Boulevard. Left turn lanes on Johnnie Dodds to Shelmore and Anna Knapp will be limited to a single lane with the provision of a turn lane if this need is determined in the future.
- Construction of a tight diamond interchange with an overpass carrying Johnnie Dodds Boulevard traffic over Bowman Road. The interchange will carry three lanes in the southbound direction and two lanes in the northbound direction. Bowman Road will be widened to six lanes under Johnnie Dodds Boulevard with appropriate transitions to the existing lane configurations. Click here to view. (updated February 2010)
- Where needed in high traffic volume areas, traffic signals will be installed where the frontage road intersects with the side roads. An exception to this will be those intersections restricted to right in-right out operation on the east side of the Bowman Road interchange. These intersections will remain in their current location with the exception of the west quadrant of the Bowman Road interchange, which will be relocated farther away from Johnnie Dodds Boulevard in conjunction with the relocation of Hospital Road.
