The Ada County Highway District and the city of Meridian will break ground on a complex road widening and sewer and water project on Oct. 29.

During the one-year-long construction project, Meridian Road will be closed between the railroad tracks to just south of the Meridian Road and Cherry Lane intersection.

On Wednesday, businesses and residents are invited to attend a meeting to learn how the project will be built. The meeting will address construction phasing, anticipated impacts, including short-term intersection closures, accessing businesses and residences within the closed section of Meridian Road, and ways to stay informed during the project. Following a brief presentation, attendees will have an opportunity to ask questions of ACHD, Meridian city staff and the general contractor. The meeting takes place at City Hall, 33 E. Broadway Ave.

Businesses are invited to attend from 5 to 6 p.m.; the general public is invited to attend from 6 to 7 p.m.

The same presentation will be given at both meetings.

The Meridian split corridor, phase two project and the Meridian Public Works project will:

• Widen Meridian Road to five lanes between Franklin Road and Cherry Lane to include two lanes in each direction and a center turn lane.

• Construct a crossover roadway, connecting Main Street and Meridian Road, just south of the railroad tracks.

• Add 7-foot-wide sidewalks on Meridian Road.

• Rebuild the Main/Fairview and Meridian/Cherry intersections

• Upgrade Meridian sewer and water services to increase capacity and enhance services. Phase one of the Meridian split corridor project was completed in August 2009 and created a one-way couplet on Main Street and Meridian Road between Interstate 84 and Franklin Road.

Information presented at the Oct. 17 public meeting will be posted to the project website, www.meridiansplitcorridor.org, and to www.achdidaho.org/projects where project information and resources such as business access maps and short project videos are available.
