Q. Is there any plan to replace the damaged concrete curbing around the edge of the roundabout in front of the main entrance into I’On? Gretchen Kayor, Mount Pleasant
A. “We will contact the South Carolina Department of Transportation maintenance office that oversees maintenance on Mathis Ferry Road to determine when they may have plans to repair the curbing. Thank you for bringing this situation to our attention.” - Ed Barbee, CPPB, Transportation Construction Liaison, Town of Mount Pleasant
Q. Prior to starting road improvements on Highway 17 the part of Long Point Road from Whipple to Highway 17 was marked as a “Scenic Highway…No trucks six wheels or over allowed.” Gary Canady, Mount Pleasant
A. “There are two signs in place on US Highway 17 prohibiting truck traffic on Long Point Road. One sign south bound on the right shoulder of US Highway 17 just before Long Point Road and the other is located north bound in the median just before the start of the dedicated left turn lane onto Long Point Road.” - Ed Barbee, CPPB, Transportation Construction Liaison, Town of Mount Pleasant
Q. When driving north on US Highway 17 near the I-526 overpass to Hungryneck Boulevard, there is no sign to indicate the right turn onto the ramp leading from US Highway 17 North to Hungryneck. When is this sign going to be installed? Bill Major, Mount Pleasant
A. “According to the contractor the sign is on order and should be installed within the next two weeks.” - Ed Barbee, CPPB, Transportation Construction Liaison, Town of Mount Pleasant
Q. When will the lights on Highway 17 be regulated? They seem to be very short and traffic is backing up a lot. I understood they were spending $1 million to regulate the lights? - Pricilla Shumway, Mount Pleasant
A. “An adaptive signal system was installed and is operational for all of US Highway 17 from the base of the Ravenel Bridge to the most northern signal at Carolina Park (19 signals over about 10 miles). We have seen very good results from the system, which is designed to progress platoons of traffic for large portions of the corridor.
It does this by continually monitoring traffic volumes and creating coordinated timing plans on a cycle-by-cycle basis that progress a platoon of vehicles through the signals.
Because the system assumes fixed travel times between signals and platoons can have inconsistent speeds and naturally disperse over longer distances, there are times when an entire platoon of vehicles will not progress through.
Additionally, there are some intersections with heavier volumes that can become more congested at times, which makes progression more difficult, but these are being monitored for fine-tuning to make improvements where possible.” - Brad Morrison, Director of Transportation, Town of Mount Pleasant
Q. What is the construction timetable for the new roundabout on Needlerush and Longpoint Road? - Lisa Schnipke, Mount Pleasant
A. Underground utility work has begun there and construction of the actual round-about is scheduled for completion in the September time-frame, according to Town of Mount Pleasant Transportation engineer Paul Lykins. The bulk of the work will be done by the time school starts in August.
The $1 million project is being done by Gulf Stream Construction.
Most of the work will be done at night because of South Carolina Department of Transportation lane closure restrictions. The completed round-about will feature a single lane through for east-bound traffic (heading toward Boone Hall Plantation).
