H-3 was a military built project. Many Native Hawaiians didn't want it but I believe the purpose of the highway was to be able to quickly deploy troops and equipment between Kaneohe Marine Base Hawaii and Pearl Harbor. 
H-1 was a poorly designed project from the start. The on/off ramp system between Middle Street and Punahou are not properly designed. The engineers thought they were outsmarting the ones on the mainland. Also, due to the current configuration I don't believe we are able to get Federal funding to fix it. 
One of the problems here are the voters. A large portion or the population are so Pro Democrat that they will vote for them regardless of the issues they support. As we have even found out, they will even vote for a dead candidate. How's that for responsible voting? You may or may not know that a large portion of the population of Hawaii are either goverment workers or in a union. One wouldn't be far off saying the unions control politics here.
