LRCT connects Charleston and North Charleston along a corridor that parallels Interstate 26, one of the region’s primary commuter routes. The transit project connects major destinations including hospitals, universities, employment centers, and historic downtown Charleston.

Bus rapid transit was selected because it improves travel time and reliability while remaining flexible enough to adapt as the region grows. Dedicated bus lanes, enhanced stations, and transit signal priority allow buses to move more efficiently through traffic while providing a higher level of service than traditional bus routes.

Together, these features create a mass transit system designed to function as a reliable alternative to driving along one of the region’s most congested corridors.

LCRT follows Charleston Area Regional Transportation Authority (CARTA)’s most heavily used route. Before the pandemic, the corridor carried nearly two million riders each year, all operating in mixed traffic. Bus rapid transit helps meet these diverse travel needs by providing frequent and reliable service.

The system will operate up to 21 hours per day with 10-minute peak headways. End-to-end travel time is projected at about 70 minutes. During peak congestion, driving the same trip can take significantly longer due to traffic, bridge constraints, and limited alternate routes.

Dedicated bus lanes and signal priority help buses move more efficiently and maintain consistent travel times.

Early planning evaluated several high-capacity rapid transit line systems, including commuter light rail. Bus rapid transit emerged as the preferred solution because it offers the right balance of performance, flexibility, and cost for the Charleston region.

These characteristics are particularly significant in the Lowcountry, where the historic peninsula features one-way and narrow streets, an irregular street grid, and frequent high-tide flooding that can disrupt travel. Additionally, bridges and waterways restrict alternate routes when incidents occur.

Bus rapid transit allows vehicles to detour when necessary and continue serving riders even when roadway conditions change. The system can also expand more easily as development and population growth continue along the corridor.

For a rapidly growing region approaching one million residents, that flexibility makes bus rapid transit a practical long-term investment.

LCRT incorporates several features that improve transit performance. Dedicated bus service lanes cover more than half of the corridor, allowing buses to operate separately from general traffic. In mixed-traffic sections, transit signal priority helps buses move through intersections more efficiently.

Stations support faster boarding and accessibility. Level boarding, all-door boarding, and off-board fare payment reduce dwell time and improve the rider experience.

The system includes 20 stations spaced roughly two miles apart and supported by local feeder service. Stations will also include fare vending, Wi-Fi, improved pedestrian crossings, and connecting sidewalk and shared-use paths to support safe access.

LCRT is advancing through the Federal Transit Administration’s Capital Investment Grants program. The project completed Alternatives Analysis in 2016 and moved into project development and engineering. The project is expected to complete construction in 2029, followed by system testing and commissioning, with revenue service projected to begin in 2030.

The total project cost is approximately $625 million. Federal funding provides about $375 million, while a voter-approved half-cent transportation sales tax provides the local match. Securing the local funding early helped the project to compete successfully for federal investment.

LCRT relies on coordination among several agencies. The Berkeley-Charleston-Dorchester Council of Governments serves as project sponsor and program manager. The South Carolina Department of Transportation leads engineering and construction, while CARTA oversees transit operations. Charleston County provides local funding. Each partner contributes its expertise to support successful delivery of the project.

As Charleston continues to grow, the region needs transportation solutions that improve reliability without relying solely on roadway expansion, and LCRT provides that alternative. Dedicated lanes, frequent service, and coordinated planning allow buses to move more efficiently through one of the region’s most congested corridors.

By combining the flexibility of bus operations with the performance of bus rapid transit, LCRT strengthens connections between communities and key destinations across the Lowcountry, resulting in a more reliable transit option that supports mobility today while preparing the region for continued growth.
