 The Tennessee Department of Transportation (TDOT) is widening Franklin Road between Concord Road and south of Moores Lane. The planned improvements include: Widening the roadway from its current two/three lane configuration to a five lane configuration with two north and south bound through lanes and a center turn lane.  The project will also include a multi-use path on the east side. 

TDOT started work in September 2017 and is expected to take three to four years to complete.

Progress

  1. Since the beginning of the project, retaining wall #7 is partially complete just north of Ellendale Dr. The remainder will be completed as the road is constructed through that area.
  2. The contractor has also completed two box culvert extensions for new drainage on each side of the road just south of Ellendale Dr.=

   Current work (April 2018 update)

  •  -The lane shift at the Concord Rd intersection is complete and crews will begin utility and grade work on the east side of Franklin Rd.
  •  -Excavation of the cut area on the west side of Franklin Rd between Ellendale and Willowick continues.  There will be intermediate stoppages of traffic in this area as trucks will pull on and off of Franklin Rd.
  •  -Retaining Wall 4 construction is approximately half way complete.  Crews suspended work on this wall due to rainy season and close proximity to a stream.
  •  -Retaining Wall 9 construction has commenced.  About 60% of the footer is poured and some wall section are also poured.  Crews will begin with the box culvert extension that ties into Wall 9.
  •  -Utility crews continue to install Brentwood Water, Brentwood Sewer, and MTEMC electric poles throughout the project.
  •  -Grading crews continue to prepare widening areas in order for storm drain installation to begin in the coming weeks.

Crockett Rd. / Green Hill Blvd. Roundabout

Construction will begin in September 2017 on a new roundabout at the intersection of Crockett Road and Green Hill Blvd/Raintree Parkway.  Civil Constructors, LLC won the low bid with their $955,025 contract. The roundabout will replace the existing four-way stop and was selected over other alternatives following extensive analysis by Brentwood’s Traffic Engineer, Mike Harris.   “Given the backup that currently occurs at the four-way stop during peak times, we had to look at ways to improve the flow of traffic. A traffic signal or a roundabout would perform equally well during heavy volume, but the roundabout significantly outperformed the signal during off-peak times and was considered the best option,” Harris explained.  The roundabout also has the advantages of lower operating cost, less impact to adjacent properties, and a higher capacity to accommodate future growth in traffic volume.

 

Why a Roundabout?

Roundabouts have been shown to be far safer than signalized intersections and have less impact on adjacent properties.  Roundabouts are safer because speeds tend to be lower and the potential for head-on collisions or side impact crashes are virtually eliminated.  Accidents that do occur tend to be less severe with far fewer injuries.  A University of Wisconsin study of 24 intersections that were converted to roundabouts found a 52% reduction in “severe crashes” after the conversion and a 9% reduction in the number of crashes.

This will be the second roundabout constructed in the City of Brentwood and was designed to mirror the roundabout completed in 2016 at Crockett Road and Arrowhead.   Also included in this project is the relocation of a City of Brentwood water line.

The project will include a three-lane curb and gutter roadway with center turn lane and intermittent raised median, as well as a 10' bike/pedestrian path behind a 5' grass strip.  Construction is expected to be complete by late 2018.SunsetRagsdaleRealignmentJPG
