Update on safety improvements at H-3 Harano Tunnels
Work will move to Kaneohe-bound side of the freeway with a single lane closure between 7 a.m. and 3 p.m. on Friday, Jan. 31.
HONOLULU – The Hawaii Department of Transportation (HDOT) provides the following update on the safety improvements on the H-3 Freeway at the Harano Tunnels. The single lane closure at the Tunnels will move to the Kaneohe-bound side of the freeway from 7 a.m. to 3 p.m. on Friday, Jan. 31.
The single lane closure will begin approximately 2,000 feet before the tunnel entrances and will end 250-feet past the tunnel exit. After Jan. 31, the regular work hours will be 7 a.m. to 3:30 p.m., Monday through Friday. This Kaneohe-bound closure is anticipated to continue into early February.
During this closure, crews will cut grooves into the concrete to improve traction of the roadway service. The safety improvements began with the regrooving of the Halawa/Honolulu bound lanes on Jan. 21. Future work will include installation of flexible plastic poles (delineators) at the edges of the travel lanes and lane markings.
In combination, the regrooving of the concrete travel lanes and the marking and delineator work are designed to improve safety by increasing the traction of the roadway and encouraging drivers to slow down. As a reminder, the posted speed limit approaching the tunnels from Kaneohe is 45 mph and the speed limit within the tunnels is 55 mph.
HDOT encourages motorists to drive with caution and plan for extra travel time during work hours. Estimated travel times and camera views for the H-3 Freeway and other Koolau routes can be found on GoAkamai.org
