Tennessee Department of Transportation (TDOT) Bridge
Replacement
Originally built in the late 50s and early 60s, the
bridges of Poplar Avenue, Norfolk Southern Railroad, and Park Avenue over
Interstate 240 in east Memphis have structural deterioration and deficiencies
that need to be addressed. Recent construction on I-240 further exposed the
needs of each bridge.
MemFix 4 is a $54 million bridge rehabilitation project to replace or repair the
four bridges using an innovative process called Accelerated Bridge Construction
(ABC). ABC requires short-term, total road closures to allow crews the space to
do their jobs and the freedom to work around the clock. The closures will also
allow construction to be finished in months instead of years.
The bridge work and the temporary closures will also allow crews to complete the
planned widening of I-240 along this section of interstate.
This project will provide a safer commute for the roughly 50,000 vehicles that
travel this section of Poplar and Park Avenues and the trains that travel this
section of the Norfolk Southern Railroad every day, as well as the 138,000
motorists who travel under the bridges on I-240. Construction is expected to be
finished by June 2019.
