US 27 Reconstruction in Downtown Chattanooga

including widening the Olgiati Bridge over the Tennessee River

The following reflects construction activity scheduled for the current time period. All work is weather dependent.

Work on this project continues.  The speed limit on U.S. 27 in the construction zone is 45 MPH.  Recently, as part of Phase 2 of the project, traffic on U.S. 27 was shifted to the outside in both directions to allow the contractor access to the middle portion of U.S. 27 for the next construction phase.  As a result of traffic shifting to the outside, the ramps at MLK Blvd. in both directions and the 4th St. ramp on U.S. 27 South were shortened and originally required traffic to yield when entering U.S. 27.  The YIELD signs have now been changed to STOP signs because of the increase in traffic crashes in the work zone.  All traffic must stop at the following locations before entering onto U.S. 27:  4th St. ramp onto U.S. 27 South, westbound MLK Blvd. ramp onto U.S. 27 South, eastbound MLK Blvd. ramp onto U.S. 27 South and eastbound MLK Blvd. ramp onto U.S. 27 North.  Drivers are encouraged to obey the signage and pay close attention to changing conditions in the work zone.  There will be increased law enforcement presence within the project limits.  The contractor may have temporary lane or shoulder closures on U.S. 27 between 7PM-6AM.  At least one lane will remain open in each direction on U.S. 27.  THP will assist with traffic control on the project as necessary.
