MERIDIAN — Improvements to two major Meridian roads may be causing some traffic headaches.
Three projects, which have led to recent closures, on Meridian and Ten Mile roads began last fall and are expected to be completed in phases by fall 2020, according to Natalie Shaver, public information specialist for the Ada County Highway District, the agency making improvements to both roads.
A section of Meridian Road between East Carmel Drive and East Fairview Drive/Cherry Lane was closed to traffic on Jan. 20. The road is expected to open this weekend, as construction crews finish replacing a culvert at the Settlers Canal, Shaver said in a recent phone interview.
“We have to do this work at certain times of the year,” Shaver said. “There’s only a small window when they can do that canal work, and it has to be done typically in the spring before the irrigation system is back on.”
The culvert replacement is one phase of the yearlong, $5.6 million project on Meridian Road between Cherry Lane and Ustick Road. In 2020, ACHD will widen that section of Meridian Road to from three to five lanes, install pedestrian signals and install new curb, gutter, sidewalk and bike lanes.
The next phase of the Meridian Road Project involves extending the bridge at Five Mile Creek, irrigation pipe installation, utility installation/relocation and road widening.
The city of Meridian contributed $550,000 to the project for “sewer and water work,” Shaver said.
The work will take place on the west side of the road, and there will be one lane of traffic in each direction, Shaver said.
A couple miles west, two projects along Ten Mile Road are underway.
The first, improvements between West Ustick and West McMillan roads, caused a closure last weekend, and that section of the road will be closed again for about one week, from Feb. 8 to Feb. 16.
The second closure originally was supposed to take place on Feb. 8 and Feb. 9, but the work is taking longer than expected, Shaver said.
Improvements on Ten Mile between Ustick and McMillan — which will cost about $6.1 million — include widening Ten Mile to two lanes in each direction with a center turn lane and installing bike lanes, curb, gutter and sidewalk. The project also includes adding continuous street lighting and signalized pedestrian crossings at the Five Mile Creek Pathway and just south of Vicenza Way, as well as two bridge replacements over canals.
Vicenza Way was closed on Jan. 31 and will remain closed until this spring, Shaver said.
Another project on Ten Mile Road, north of McMillan, is happening at the same time.
From McMillan to West Chinden Boulevard, improvements include widening the road to two lanes in each direction with center turn lane and installing bike lanes, sidewalks, curb, gutter and a new pedestrian signal.
This section of Ten Mile will be the future home of Costco Wholesale, which agreed to fork over millions to local agencies for road improvements.
Improvements to Ten Mile between McMillan and Chinden will cost about $3.9 million. Costco is responsible for about 44% of construction costs, or $1.7 million. ACHD’s portion is about $2 million, and the city of Meridian will pay about $350,000.
