Work to improve the Isle of Palms Connector starts Wednesday.
Crews will work during the day as well as at night but will only close a lane between 9 p.m. and 6 a.m., according to the announcement from Charleston County.
Here's the timeline of the project:
.Starting this week, crews will relocate and remove some trees.
.Next, a storm-drainage system will be installed and concrete sidewalks and curbs replaced.
.During February, heavy equipment will begin to move soil to construct the road shoulders and place asphalt to widen the road.
.The final pavement overlay, stoplight installation and pavement marking is expected to be concluded in April and May.
Here is an overview of the project:
.The work will include 1.3 miles of improvements including the widening of the Isle of Palms Connector in Mount Pleasant.
.Two through lanes in each direction will be built from U.S. Highway 17 to just east of Riviera Drive.
.Left and right turn lanes will be installed at each of the four intersections along the length of the project.
.The existing multi-use paths and sidewalks will be maintained and the road widening will include 4-foot paved shoulders for cyclists who prefer riding on the street.
.To maintain the existing avenue of live oak trees, 37 trees will remain in place, 16 trees will be relocated on site and 82 new trees will be planted. At completion, there will be 16 more trees along the route than are currently planted.
The project is being paid for with the county's transportation sales tax.
