State to add westbound lane on Moanalua Freeway — just in time for the new school year

HONOLULU (HawaiiNewsNow) - The state will add a new freeway lane on Moanalua Freeway going west — from Halawa Interchange Red Hill to Aiea Heights Drive Overpass.

To add the lane, crews will adjust the width of freeway lanes, move a barricade and re-stripe.

State Transportation officials estimate the new lane will carry 2,200 vehicles per hour during peak afternoon drive, speeding up the slowdown that happens in that corridor.

The state said widening the highway to add a lane would cost $280 million. Adding a lane with the existing space will cost $4 million.

"I am pleased that HDOT continues to move forward with cost-effective projects aimed at improving the daily lives of residents who travel on these roads," said Gov. David Ige, in a news release. "As we continue our search for new and innovative solutions within our means, I am excited to see projects like this that ensure the best return on highway funds that are dedicated to reducing traffic."

The new lane widths vary across the project, ranging from 12 feet to 10 feet. The narrowest lanes will be beneath the Kahuapaani overpass.

Work on the project is set to start June 5 and wrap up in August, just in time for the start of the new school year.

Crews will work on the project at night to minimize traffic disruption.
