The now nearly $19.2 million Tennessee Department of Transportation (TDOT) slide repair project begun just over a year ago on U.S. Highway 41 in Marion County has been delayed again, due to another wintertime swamping by Mother Nature. A change order for additional repairs was awarded May 28, leading the TDOT to now estimate the project will be completed at the end of October.

As part of the bridge replacement project on I-24 in Chattanooga, contract crews for the Tennessee Department of Transportation (TDOT) in late May began pile driving operations during daytime hours for bridge foundations on Germantown Road over the interstate.

The largest construction contract in Tennessee Department of Transportation (TDOT) history is currently underway near Nashville, utilizing the unique process of rubblization, which is new to the area. According to the project website, the reconstruction of Interstate 440, from Interstate 40 to Interstate 24 in Davidson County, includes removing substandard pavement and providing three lanes of travel in each direction for approximately 7.6 mi.

The collapse of the I-75 South bridge over I-24 West in Chattanooga April 1 proved to be anything but a funny April Fool's Day prank to motorists and the Tennessee DOT. All lanes at the busy interchange of I-75 and I-24 closed for several hours after the failure, stopping traffic in all directions throughout most of the day.

The concrete railing portion of a bridge collapsed, injuring one in Chattanooga, Tenn., on April 1. The incident occurred at the I-75 North and I-24 West split, and shut down two interstate ramps on what is reported to be one of the nation's busiest intersections, CNN reported.

The Tennessee Department of Transportation reopened a section of eastbound Interstate 24 two days earlier than expected following a landslide Feb. 23. The slide, which took place near mi. marker 42, dumped approximately 50,000 cu. yds. of former hillside on the interstate, covering both eastbound lanes for about three-quarters of a mi.

Long-term lane closures for heavy construction operations on the Interstate 440 reconstruction project are estimated to begin the weekend of March 1 in Tennessee. TDOT is advising drivers to prepare for increased drive times along the I-440 corridor and surrounding areas beginning in March 2019 until the project completion in August 2020.
