Crews are set to begin rebuilding the Meridian Road interchange this week, as part of a two-year reconstruction project
that began with replacement of the bridge over Ten Mile Creek in 2013 and will finish with new pavement on I-84 between Locust Grove and Five Mile Road in late 2015.
Work on the interchange will update a structure built in 1965 and intended for a vehicle load of about 15,000 a day. During the past 49 years that number has increased to more than 128,000 vehicles per day.
Improvements will include three lanes in both directions on Meridian Road, dual left-turn lanes for each I-84 on-ramp and a single traffic signal at the center of the interchange.
According to the Idaho Transportation Department, the $40 million Meridian Road project is being paid for out of $80 million in savings from the GARVEE road construction program, and is part of a yearslong effort
to widen I-84 to four lanes in both directions, east to west.
As part of the project, the Robinson and Black Cat bridges were replaced in 2009 and the Garrity and Ten Mile interchanges were replaced in 2011. In addition to Meridian Road, the Broadway and Gowen interchanges in Boise are also set to be rebuilt.
An official groundbreaking for the Meridian Road project is scheduled for Tuesday, April 15, at 1:30 p.m. in the Home Depot parking lot at 1100 S. Progress Ave.
