Heads up for I-49 drivers! This shouldn't be a big problem, but be ready for last minute lane changes in this already congested area. The right lane of I-49 will be closed in the northbound direction at the I-10 interchange for overhead sign construction on Tuesday, October 18 and Wednesday, October 19 between the hours of 8:00 p.m. and 6:00 a.m.  This closure has no vehicle restrictions. Emergency vehicles will have access to the area.  No detour is necessary.
