Trimble County: U.S. 421 Turn Lanes into Trimble County High School Project - 05 8712

​
Purpose
Improve safety along U.S. 421 by adding turn lanes into Trimble County High School.
​Type of Project
Construct a northbound left turn lane on US 421 to allow for turning vehicles into the Trimble County High School entrances.
A left turn lane is being added for northbound traffic to facilitate the turning movement into the school, but it is being extended all the way to the U.S. 421/KY 625 intersection.  That intersection provides a more logical terminus.

Based on traffic counts gathered during the preliminary design phase, a left turn lane is warranted for vehicles turning onto KY 625 from U.S. 421. 

Selected Alternative #2: Due to right of way and utility impacts, it was decided to widen to the west side of U.S. 421 only.  US 421 will taper from 2-11' through lanes to 2-11' through lanes and a 12' left turn lane within the project area. *From Alternatives below
​Project Timeline

As of Winter 2023/2024​:

  • Overhead utility relocations began in April 2023 and were completed in August 2023.​
  • KYTC has acquired all necessary right-of-way for the project.
  • KYTC let the project to construction in September 2023.
  • Construction is currently ongoing, and KYTC anticipates the majority of the road widening construction to be completed during the Summer of 2024 when school is not in session.

Non-selected alternatives

During the preliminary design process, KYTC reviewed three widening alternatives for adding a turn lane:

  1. Widen to the east side of US 421
  2. Widen to the west side of US421
  3. Widen to both sides of US 421
Selected Alternative #2: Due to right of way and utility impacts, the project team decided to widen to the west side only.  US 421 will taper from 2-11' through lanes to 2-11' through lanes and a 12' left turn lane within the project area.
