A state senator held a town hall meeting, Monday night, to address the traffic tie up that left drivers stuck for hours, as they headed toward Hawaii Kai on the H-1.

The traffic tangle that lasted for several days, as a result of the 24-inch water main that broke, along Kalanianaole Highway, on January 21st.

"It was a traffic nightmare," neighborhood board chair, Heather Lum said.

A nightmare-- Heather Lum doesn't want to repeat.

"As residents we hear water main break and we think, 'Okay' it's going to take a couple hours, it'll be slightly an inconvenience,' and then when it takes day, after day, after day.. it's like, 'Hey, who's not doing their job," Lum added.

State Senator Stanley Chang met with residents, to find out what worked and what didn't.

"Anytime that one of these situations happen we need to ensure that traffic is flowing as smoothly as possible -- that common sense measures like re-timing lights, police directing traffic other things are going to be implemented, " Sen.Chang said. "We need more contraflows. We need more detour routes. We need more notification to people on the highway.

Hawaii's State Department of Transportation was a no show at Monday night's meeting.

But other jurisdictions including the Honolulu Police Department, Board of Water Supply (BWS), and the city -- did answer questions about contraflow lanes, signage, and stand-still traffic.

"I get that there is someone specific for safety, but there is no one specific to make sure the traffic runs smoothly?" Sen Chang asked during the meeting.

The takeaway-- Sen. Chang points out that there should be more of a clear chain of command.

While BWS adds more communication early on was needed.

"Lesson learned, and here is what east Honolulu has to say.. you guys could do better, we all could do better... in terms of shutting down traffic," State Representative Gene Ward said.

While there was mention of the Joint Traffic Management Center-- which is expected to be complete by the end of this year-- Sen. Chang says a more pro-active approach is still needed.

"It's always good whenever anything happens to evaluate, what did we do well, what can we do better," Lum said.
