Interstate 40: Bridges over Buffalo River and Squeeze Bottom Lane
Humphreys County
The Tennessee Department of Transportation (TDOT) is constructing improvements to Interstate 40 in Humphreys County. The improvements include resurfacing work on I-40 and replacement of the bridges over the Buffalo River and Squeeze Bottom Lane.
Current Status: Phase 1 construction, which includes resurfacing of I-40 from east of the Buffalo River bridge to just west of the Squeeze Bottom Lane bridge, is currently underway in preparation for implementation of traffic shifts.
Construction start: Summer 2024
Estimated completion*: January 2029
Funding Type: State and Federal
Traffic Impacts
There will be temporary lane closures in both directions on I-40 for roadway maintenance as needed (MM 140 -142). One lane will remain open.
A traffic shift is scheduled for Thursday, September 4, moving westbound traffic to the inner median so crews can work on the outside lanes.
History and Background
The 1.96-mile project on Interstate 40 in Humphreys County, from near Exit 137 to near Exit 143, consists of widening the roadway and replacing two bridges. The planned improvements are designed to replace the two bridges and improve future capacity of I-40.
Environment
As part of the environmental review process for this project, TDOT has documented commitments to environmental mitigation and remediation measures. View the commitment document here.
