Charleston City Council will spend $75,000 on a study to see how the James Island connector can be made safer for bicycling.
Council approved the expenditure this week for Stantec Consulting Services of North Charleston.
The study will review crash histories on the bridge, including for vehicles, bicycles and pedestrians.
Other areas will investigate lane widths, reducing speeds, age restrictions, safety equipment and adding more signs.
Charleston officials want to open the bridge from James Island and West Ashley into downtown for cyclists. While biking is officially illegal on the bridge, it remains a common occurrence.
In July 2011, anesthesiologist and cyclist Dr. Mitchell Hollon was killed by a work van on the connector.
