King Street Exit Ramp from I-26 to Close for Drainage Work

Construction on Phase 3 of the $146 million Spring/Fishburne Drainage Improvement Project has begun, and the work requires the closure of the exit ramp from I-26 eastbound to King Street, starting the evening of Monday, Jan. 9.

The City of Charleston will hold a ceremonial groundbreaking for Phase 3 of the project at 11 a.m., Friday, Jan. 13, at Harmon Field (at the corner of President and Fishburne Streets).

This phase of the drainage work includes the construction of two large tunnels up to 150 feet below ground surface. Eventually, these tunnels will connect to a pump station—to be built in a later phase of the project—that will hold three pumps, each capable of pumping 120,000 gallons of stormwater per minute.

City of Charleston senior engineering project manager, Steven Kirk said, “We are excited to begin Phase 3 of the Spring/Fishburne Drainage Improvement Project—the largest drainage project in the City’s history. At the completion of all five phases, approximately 260 acres will experience direct drainage improvements, positively impacting nearly 20 percent of the peninsula. This phase, which includes the construction of massive stormwater tunnels, is a critical component of long-term drainage relief in the area.”

Shafts must also be constructed for workers to access the tunnels and for conveyance and retrieval of the equipment required to build the tunnels.

The location of one of the shafts requires the closure of the exit ramp through the duration of phase 3, which is expected to continue into the summer of 2019.
