Construction Start: October 29, 2012
Project Completed: September 19, 2013
The Meridian Split Corridor Phase 2 project was substantially completed and opened to traffic on Thursday, September 19, 2013.
Some additional finishing work will occur within the project area over the next month, but is anticipated to have minimal impacts on traffic.

Project dedication - Sept. 19, 2013

The Meridian Split Corridor, Phase 2 project and the City of Meridian Public Works Sewer and Water project:
  • Widened Meridian Road to five lanes between Franklin Road and Cherry Lane
  • Constructed a cross-over roadway, connecting Main Street and Meridian Road, just south of the railroad tracks
  • Added 7-foot-wide sidewalks on Meridian Road
  • Rebuilt Main/Fairview and Meridian/Cherry intersections
  • Made upgrades to Meridian sewer and water services to increase capacity and enhance services

Intersections to Re-Open Wednesday

Motorists traveling through two busy intersections in Meridian will notice a big reduction in delays Wednesday morning when all travel lanes at the Fairview/Main and Meridian/Cherry intersections open to traffic.

The intersections have been under construction since late February as part of the Meridian Split Corridor Phase 2 project. The intersections were widened to include additional thru and turn lanes to accommodate the new Meridian Road configuration, which includes five lanes from Cherry Lane, south to the railroad tracks.

While work at the intersections will be finished, other portions of the project remain under construction; however, substantial completion is planned for Sept. 19. Some finishing work will continue at the roadside.

No September Town Hall Meeting: Due to the substantial completion of construction on Sept. 19th, no additional project town hall meetings are planned.

Meridian Split Corridor Project Set to Finish in Mid-September; Traffic Change for Main Street

On August 22 at 10 p.m., the southbound lane on Main Street between Broadway Avenue and Franklin Road was closed to thru-traffic as crews finish the new cross-over roadway of the Meridian Split Corridor Phase 2 project.

Southbound motorists on Main are being diverted west on Broadway, and south onto Meridian Road. One lane will remain open for northbound traffic on Main; access to Main Street businesses between Franklin and Broadway will also remain open during this phase of work.

Crews will work within the southbound travel lane on Main as they finish construction on the cross-over road, located between the railroad tracks and King Street. The cross-over road will link Main Street to Meridian Road. Once complete, the two-lane road will divert most northbound thru-traffic from Main Street to Meridian Road, which will become the primary north-south route for moving vehicles.

The southbound detour off of Main Street will be in place until the project is finished in mid-September.

The $8.5 million project to widen Meridian Road and make major upgrades to the City of Meridian sewer and water services began in October 2012. The year-long project is anticipated to complete one month ahead of schedule.

As with all construction, timelines are subject to change.

Note: Due to project completion anticipated for mid-September, there will not be a September Town Hall meeting

Additional Lane Restriction Planned at Main/Fairview Intersection: Expect Delays

As part of the final phase of intersection paving at the Meridian/Cherry and Main/Fairview intersections, beginning August 2, crews will begin excavation in preparation to place concrete near the Main and Fairview intersection.
Because of the work, it is necessary to close the right turn lane on the south leg of the Main/Fairview intersection. All movements (right turning, left turning and thru) will share one lane of traffic, which is anticipated to create traffic back-ups and delays.

Crews anticipate they will begin placing concrete on August 21st. A two week curing period will be necessary before traffic will be permitted to drive on the new concrete. The intersection work is expected to be complete in mid-September.

The finished intersection configuration will remove the “free running right turn” currently in place. To increase safety, the free running right turn will be replaced with a designated right turn lane when the work is complete.

(updated 7/23/2013)

This morning, Meridian Road was re-opened with limited access between Cherry Lane and Pine Avenue to accommodate businesses and neighborhood traffic at the north end of the project. One through-lane is now open in each direction. In addition, side streets between Cherry and Pine are now accessible to business and neighborhood traffic.

Open with Delays

The area will continue to be a very active construction zone with crews and large equipment working alongside the road and intersections. At times, flaggers may direct traffic on Meridian Road between Cherry and Pine, and delays are possible.
We realize it may be tempting to use the re-opened section of Meridian Road as a through route; however, motorists are discouraged from doing so, as traffic signals will not accommodate heavy traffic flows in their current configuration. Through-traffic using Meridian Road will result in significant back-ups and delays due to signals that will continue to favor east and westbound traffic, where the demand is greatest.

What’s Ahead?

Crews continue to work toward a mid-September project completion, which is approximately one month ahead of schedule.

Upcoming work will include:
- Placement of curb and gutter on the new crossover roadway – this week
Final concrete paving at the Meridian/Cherry and Main/Fairview intersections – late July
    o A traffic shift will occur prior to the work. Please use caution.
Asphalt paving between the railroad tracks and Franklin Road – targeting mid-August
Asphalt paving of crossover roadway – targeting mid-August

As with all construction, timelines are subject to change.

Signal Timing in the Area

With work underway at the Meridian/Cherry and Main/Fairview intersections, we appreciate everyone’s patience with the necessary signal timing adjustments.

We recognize that the intersection work is also impacting surrounding alternate routes. ACHD traffic signal engineers have transitioned to these parallel routes (Ustick/Pine/Franklin) to further optimize timing. We have received many good ideas from the public for signal adjustments and are working through them.

What can be done about the signal timing at Pine and Main?
The signal at this intersection favors Main Street traffic, as Main Street is the primary north/south roadway and is taking on even more traffic while Meridian Road is closed.

In addition, the Main/Pine traffic signal is coordinated with the nearby traffic signal at Main/Broadway – this requires there be a guaranteed amount of green time for the north/south movement at both traffic signals. Any additional time given to Pine would have to come from the Main Street movements which, in turn, would create additional delay.

Unfortunately, there is a limit to the relief that additional signal timing can bring under these construction circumstances. Motorists should continue to anticipate delays at the Fairview intersections as well as throughout the project vicinity.

Project Progress

We continue to hear that people want this project to be done quickly as possible – and we share that desire. In August 2011, 60% of respondents supported a closure of Meridian Road to get the project done as quickly as possible. In working to do so, certain closures are necessary for short periods of time to speed up construction. We realize this inconveniences many people; however these measures are needed for the safety of the construction crews, traveling public, and businesses.

We appreciate your patience as we continue to work through this complex project. At this time, we are still on schedule for an October project completion.

The safety of the public and construction crews is a top priority during construction. We appreciate your cooperation.

Town Hall Meetings - No September Town Hall Planned
With a planned project completion of mid-September, no town hall meeting is planned.

Town Hall meetings will be held each month during construction and are an opportunity for residents and businesses to learn about the project progress, upcoming milestones and ask questions of ACHD and Meridian City staff and the general contractor.

Materials from the Town Hall meetings will be posted to this page the following day. If you have questions about information included in the presentation, please e-mail or call 387-6100.

Location: Meetings will be held at Meridian City Hall (33 E. Broadway, Meridian) in the room off of the front doors to the right, unless otherwise specified.
