Beginning around 9 p.m. on Aug. 12, construction crews will begin shifting traffic between Murphy Road and Brightwood Avenue to the inside lanes to work on the corridor's outside lanes, according to TDOT. All traffic on I-440 will shift to the inside lanes by the end of September, officials with the transportation agency said.
"The majority of traffic has been on the outside lanes [during the project]," said Will Reid, TDOT's assistant chief engineer of operations. "Beginning Monday night, we're going to shift the traffic lanes to the inside of I-440 starting around the West End area all the way to the bridge on Brightwood [Avenue.]"
Since March 1, crews have been working 24 hours a day, six to seven days a week to replace deteriorating concrete pavement with asphalt, according to TDOT. The project, which is expected be finished by late July 2020, also includes upgrading the entire roadway to three lanes in each direction and widening the I-440 bridge over I-65.
Reid said he encourages drivers to seek alternate routes around Nashville to avoid the construction zone on I-440. For those who do travel on I-440, he said drivers should maintain a maximum speed limit of 45 mph throughout the duration of the project.
"For [TDOT] employees and the project's contractor employees, [I-440] is their office, so please obey the speed limit of 45 mph," Reid said. "One of the best things drivers can do is avoid I-440 and choose an alternate route if at all possible."
Within six months of major construction work, TDOT said contractors have reached the following milestones:
- 100,000 tons of old concrete pavement have been recycled to be used for the new roadway base.
- 68,000 tons of new permanent asphalt pavement have been laid on the roadway.
- More than 200 people are working on the reconstruction project.
