State Board approves locations for eastern Idaho interchanges
RIGBY - Locations for the Menan-Lorenzo and Thornton interchanges on U.S. 20 in eastern Idaho were approved today by the Idaho Transportation Board at its regular monthly meeting, the Idaho Transportation Department announced.
The board approved alternative ML-A for the Menan-Lorenzo Interchange to be located north of Rigby and south of the Snake River. ML-A will connect to 700 North (Menan-Lorenzo Highway) and LaBelle Road.
Option T-G was approved for the Thornton Interchange. T-G is located north of the community of Thornton and will connect to 3300 West and 4700 South.
Completion of these interchanges will eliminate all remaining at-grade crossings between Rigby and Rexburg, improving traveler safety on U.S. 20 and county roads.
A public hearing was held June 23, where potential locations for each alternative were presented. Public comment along with engineering feasibility, environmental impacts and cost were weighed in selecting the alternatives that best meet community needs.
Construction of the Menan-Lorenzo Interchange is planned for 2008. Final design and purchase of right-of-way will begin immediately.
The Thornton Interchange project is listed in the State Transportation Improvement Program in preliminary development with no date for construction; however, ITD will begin the final design for the Thornton Interchange and purchase needed right-of-way.
