The Idaho Transportation Department is replacing the outdated and undersized Interstate 84 Meridian Road interchange.
Construction on the $40 million project will start in early 2014.
On Wednesday, July 24, ITD will present design plans during an open house from 4 to 7 p.m. at Wahooz Family Fun Center, 1385 S. Blue Marlin Lane. Materials and information from the open house also will be available via an online meeting from July 25 to Aug. 8.
The new Meridian interchange will be a single-point urban interchange (SPUI). The SPUI design offers efficiency by using one signal in the middle of the interchange and improves traffic flow and movement of vehicles. Similar interchanges were built at Vista Avenue in Boise and Ten Mile Road in Meridian.
The project also will include widening I-84 to four lanes under the interchange and adding curb, gutter, sidewalks and bicycle lanes 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 travel over, under and on and off the interchange each day. Today, that number has increased to over 128,000 vehicles.
ITD also is replacing the I-84 interchanges at Broadway Avenue and Gowen Road and adding a third lane on I-84 between Broadway and Gowen.
