The Idaho Transportation Department is planning to replace the Interstate 84 Meridian Road interchange in spring 2014.
The public can preview the project at either of two public open houses Wednesday or Thursday, March 20 and 21, from 4 to 6 p.m. at COMPASS, 700 N.E. 2nd St., in Meridian. During the open house, ITD will present preliminary design plans for the new interchange, gather comments and answer questions.
ITD will build a new single-point urban interchange (SPUI) at Meridian Road. This interchange design uses one signal in the middle of the interchange. ITD built similar interchanges at Vista Avenue in Boise and Ten Mile Road in Meridian.
I-84 will be widened to four lanes under the structure. As part of the project, curb, gutter, sidewalks and bicycle lanes will be added on Meridian Road. ITD and the city of Meridian are working together to determine landscaping, lighting and other aesthetic features for the interchange.
The current interchange was built in 1965 when approximately 10,650 vehicles traveled over, under and on and off the interchange each day. Today, that number has increased to over 128,000 vehicles. The new interchange design will improve traffic flow and the movement of vehicles on and off of I-84.
The Meridian Road interchange replacement and the widening of I-84 will cost approximately $40 million. Plans also are under way to replace the interchanges at Broadway Avenue and Gowen Road and add a third lane on I-84 between Broadway and Gowen in 2014.
