Recommendations for improving transportation along the Interstate 526 corridor, between Rivers Avenue in North Charleston and Savannah Highway in West Ashley, will be explored at a meeting Tuesday evening in North Charleston.

The South Carolina Department of Transportation commissioned the study three years ago, hiring a consultant "to consider all available options to reduce traffic congestion along the corridor" according to an SCDOT statement late Monday.

The options, the department said, "included lower cost transportation such as ride-sharing, transit incentives, telecommuting, flex time, and increased biking and pedestrian facilities; modal improvements such as transit, trucking, rail and shipping; traffic operating strategies such as interchange improvements and signal changes; and capacity improvements such as adding lanes and widening roadway."

Last year, about $150 million for I-526 improvements was included in the Statewide Transportation Improvement Program. Most of the funds, $120 million, were meant to be used for creating a better interchange for Interstates 526 and 26.

Charleston-area officials also asked SCDOT last year to consider a plan to widen the entire completed portion of I-526, which runs about 19.5 miles from West Ashley to Mount Pleasant. The proposed project would cost about $534 million.

The SCDOT has scheduled a two-hour meeting to make the results of the corridor study public and answer questions, from 5:30 to 7:30 p.m., with a formal presentation at 6 p.m., in City Council chambers at North Charleston City Hall, 2500 City Hall Lane.
