The Patriots Point Gateway Intersection Improvements project enhances one of Mount Pleasant’s most visible and heavily traveled gateways, located at the base of the Arthur Ravenel Jr. Bridge and adjacent to major regional destinations including the USS Yorktown, Patriots Point Naval & Maritime Museum and nearby parks and mixed‑use districts. STV provided full design services to widen the roadway, improve intersection geometry and strengthen multimodal connections for pedestrians, cyclists and transit users. The project improves traffic operations while creating a safer and more accessible entry point for residents, commuters and visitors traveling between Mount Pleasant and Charleston.
What challenges did STV address?
The intersection serves high traffic volumes, is a major tourist destination, and is constrained by a coastal right-of-way prone to drainage challenges. STV needed to increase vehicle capacity while designing multimodal facilities consistent with Mount Pleasant’s long‑term mobility and resilience goals. Maintaining safe truck and bus movements near the Ravenel Bridge approach and integrating new pedestrian and bicycle links into an existing urban network required precise coordination and modeling.
What solutions did STV deliver?
STV redesigned the intersection with widened travel lanes, sidewalk‑level separated bike lanes, raised pedestrian crossings and upgraded sidewalks. The team incorporated four floating bus stops and two new solar‑powered shelters to support MBTA Silver Line operations. A unique “bike box” provides a two‑stage left turn movement for cyclists, improving safety at conflict areas. Pervious pavers with an underlying basin enhance drainage performance and stormwater resilience. STV also provided roadway design, traffic engineering, stormwater management, permitting, utility coordination and construction administration.
How does this project benefit the community?
The improvements create safer routes for pedestrians and cyclists, reduce congestion at a major regional gateway and strengthen access to key destinations along Charleston Harbor. By integrating innovative multimodal design features, the project enhances quality of life, supports tourism and improves long‑term mobility in a growing coastal community.
