Traffic Impacts

8/26 – 8/28, 7 p.m. – 5 a.m.: There will be nightly lane clsoures on I-40 eastbound to set barrier rail and install attenuators. One lane will remain open. Signage will be in place as well as queue warning trucks alerting motorists to any stopped traffic ahead. It is important to note there is also nightly paving work happening on I-40 at MM 126 to the Tennessee River Bridge in Benton County (Region 4) that could also impact travel in this area.
