Johnnie Dodds improvements to affect appearance of Mount Pleasant

Following years of speculation and planning, the stretch of U.S. Highway 17 extending through Mount Pleasant will experience an extensive makeover beginning late this summer.

The Charleston Metro Chamber of Commerce’s Developers Council met this morning to reveal the final decisions regarding several Charleston area roadway improvements.

Paramount in the discussion was the renovation plans of Johnnie Dodds Boulevard from the foot of the Arthur Ravenel Jr. Bridge to just north of the Interstate 526 interchange in Mount Pleasant.

The need for improvements along this stretch of highway has been an issue since a 2000 transportation plan study highlighted the town’s need to widen its main roadway to avoid congestion caused by a high volume of traffic.

The project is estimated at $80 million and includes widening the stretch of U.S. Highway 17 to three lanes in each direction and adding bike lanes and sidewalks along the frontage roads. The renovation also calls for an overpass carrying traffic over Bowman Road and extensive modifications to the intersections at Anna Knapp Boulevard and Shelmore Boulevard.

The development effort not only affects the highway’s commuters, but also the overall appearance of the town along that route.

“The town of Mount Pleasant will likely shift its development focus over the long term,” said Jim Fisher of TranSystems, lead engineer for the project’s preliminary design.

The new layout will encourage the town to stimulate development along the frontage roads, as the proposed improvements would make storefronts and offices in this area more visible and accessible, Fisher said.

Fisher also noted the town will add more prominent signage to welcome incoming traffic as well as a “way finder” system that will direct commuters to specific sites, shopping centers and hotels.

A major challenge engineers have faced is the limited right of way available to widen the roads in certain areas. Some buildings will be within feet of the frontage roads following the proposed project.

The primary source of funding for the project is the Charleston County Roadwise’s half-cent transportation sales tax. The county began collecting the tax in May 2005 to fund an array of Charleston County road improvements.

“About $70 million of the $80 million required for completing the project has been budgeted for and funded by the Roadwise transportation-half cent sales tax,” said Fisher, emphasizing that the estimate of the project’s final cost is closely in line with Charleston County Roadwise’s budget.

Fisher also noted that federal requirements have been considered so that if there is a need for funds in the future, they have the means through which to acquire them.

The project is expected to start in August.
