The Idaho Transportation Department on Sunday night will begin a six-month-long construction project to improve Eagle Road between Fairview Avenue in Meridian and State Street in Eagle.

All construction will take place at night to avoid major traffic disruptions.

Eagle Road from Fairview to State will be resurfaced and six-inch-tall concrete medians will be installed from Franklin Road to Oakhampton Drive, just north of Chinden Boulevard. Raised medians also will be added east on Chinden at the intersection with Eagle Road to the Target entrance. Medians will not be installed on north section, which runs through Eagle.

The $4.7 million construction project will be completed in three phases.

• June 11 to mid-July: Continuous raised medians will be constructed from Franklin Road to River Valley Street. Fairview Avenue to River Valley Street will be repaved.

• Mid-July to late September: Continuous raised medians will be constructed from River Valley Street to Oakhampton Drive and the roadway will be repaved.

• Late September to mid-November: Continuous raised medians will be constructed from Oakhampton Drive and Idaho 44 and the roadway will be repaved.

To reduce traffic interference, crews will complete each phase before moving onto the next phase.

Eagle Road will remain open at all times during construction, which will occur at night with lanes restricted from 9 p.m. to 5 a.m. At least one lane in each direction will remain open during the overnight work. No lane closures or restrictions will occur between 5 a.m. and 9 p.m. Access to businesses and residences will remain open from 5 a.m. to 9 p.m. Access may be temporarily restricted during nighttime repaving operations.

The speed limit will be reduced to 45 mph in the construction zone.
