ACHD has four major road widening projects in the works for 2019, with 300 more that will be designed or built in the next five years, according to Head.
Those four major projects are:
- Widening Cloverdale to five lanes between Ustick Road and Chinden Boulevard. ACHD officials are working jointly with the Idaho Transportation Department on the Cloverdale overpass on Interstate 84.
- Widening Linder Road to five lanes between Ustick Road and Chinden Boulevard.
- Widening the Cole Road and I-84 on/off ramps intersections, which would ease the traffic choke points on Cole Road, according to Head.
Their other main project is the widening of State Street and Collister Drive, which followed the expansion of the State Street and Veterans Memorial Parkway intersection last year.

Widening those State Street intersections will help with congestion and improve Valley Regional Transit's route, but the ACHD's plans are still short of what their forecasts and models (provided by the Community Planning Association of Southwest Idaho), show what was needed to keep up with growth.

In fact, the Treasure Valley could eventually reach a tipping point where it won't be possible to build more roads to alleviate traffic snarls, according to Head.
"You can't build your way out of congestion and at some point, we just have to manage it whatever means we can," he said.
