Update 10 a.m. Sept. 16:
The Idaho Transportation Department announced late Sept. 15 that it would not reduce lanes along I-84 between Boise and Meridian during daylight hours.
An "eleventh hour" decision reached by ITD and its contractor, Concrete Placing Company, means rebuilding outside lands and shoulders at the Meridian Interchange will not require closing additional traffic lanes during the day.
The change comes after ITD redirected crews rebuilding the interchange to construct outside lanes and shoulders along the interstate's westbound side, rather than crews working both east- and westbound sides of the road simultaneously.
When crews have completed work on the westbound side, they will begin on the eastbound side.
Original post 12:11 p.m. Sept. 15:
The Idaho Transportation Department, along with the Boise Metro Chamber of Commerce, cut the ribbon Sept. 15 on two improved I-84 interchanges, as the Ada County Highway District announced the closure of a lane on I-84 itself.
The interchanges, located along I-84 at Gowen Road and Broadway Avenue, have been widened to safely increase traffic flow and improve efficiency along two high-volume roads.
ITD rebuild the interchange at Broadway Avenue in the model of a Single-Point Urban Interchange, like the infrastructure of the intersection of Vista Avenue and Ten Mile Road. At Gowen Road, a diamond interchange has replaced the previous on- and off-ramp connections, and the ramps themselves were widened. In addition, bicycle lanes, sidewalks and gutters have been installed at both interchanges to accommodate all users as they cross the freeway.
"I-84 in the east Treasure Valley is the gateway to Boise, Boise State University, and our vibrant downtown area. These two new interchanges will meet our transportation needs and position the entire community for further economic growth and prosperity," wrote Boise Metro Chamber of Commerce President & CEO Bill Connors in a press release.
Just as those interchanges open, ACHD warned motorists of a lane closure on I-84 set to begin Wednesday, Sept. 16, and remain in place through November. A news release from ACHD said to expect more traffic and delays along alternate routes including Overland, Franklin and Ustick roads, as well as Fairview Avenue, Chinden Boulevard and State Street.
As a result of the increased traffic along these thoroughfares, ACHD will monitor traffic via live camera and adjust traffic signals to enhance usability.
