Starting July 30th for a six month trial period, Department of Transportation is shutting down the Piikoi on-ramp to the H-1 Freeway East-bound from 3 to 6 p.m. on weekdays.

That's peak hours because a study released back in April showed closing it at that time would increase traffic flow with minimal impact on surrounding streets.
Data showed drivers could save about six minutes between the Fort Shafter overpass and Punahou off-ramp.

And on side streets the impact was less than one minute.

"When we had restricted the usage for the Piikoi on-ramp, we saw that we didn't have people jumping over two lanes to stay on the freeway anymore," said Ed Sniffen of the Department of Transportation. "So, that weaving action... that potentially dangerous action is eliminated now. So, we thought this is a perfect time to start pushing this forward again."

Alternate routes to the H-1 East-bound include Vineyard, Ward and University.

Signs will be posted throughout the area, and when the trial period is over, the Department of Transportation will determine weather or not to make the change permanent.
