A Kalihi Street improvement project beginning this weekend will cause nightly lane closures for about a week.

Two southbound lanes will be closed between School Street and the H-1 freeway nightly from 7 p.m. to 4:30 a.m. The closures will begin Sunday night and end Friday morning.

The $3.2 million improvement project involves resurfacing, the reconstruction of weakened pavement areas, installation of loop detectors, pavement striping and signage, among other improvements. While the closures will last only one week, the project’s expected completion date is by the end of the year, weather permitting.

“Not only will this project benefit motorists, but it will also focus on pedestrian safety because of the high volume of students accessing Kalihi Kai Elementary School, Kalakaua Middle School, and Farrington High School,” said state Highways Deputy Director Ed Sniffen.

State officials are considering raised crosswalks and new traffic signals, as well as the relocation of a bus stop near Ashford Street behind the sidewalk to provide a wider walking area.
