Hundreds of drivers use Exit 11B every day, so the shutdown is sure to cause some traffic congestion.

CHARLOTTE, N.C. — Some I-77 drivers may be in for a rude awakening on Thursday.

Exit 11B will be closed; that's the busy ramp from southbound I-77 to westbound Brookshire Freeway near uptown.

Hundreds of drivers use that exit every day, so the shutdown is sure to cause some traffic congestion.

Drivers will have to use the eastbound detour to northbound North Graham Street. Traffic will then take the entrance ramp to westbound I-277 at West 12th street to access westbound I-277.

Here is the detour map:

Crews will be constructing a new noise wall adjacent to the ramp.

Exit 11B is expected to close for two months. Exit 11A from I-77 southbound to the I-277 inner loop will remain open.
