The on and off ramps from the H-1 Freeway at Punahou Street will remain closed between 9 a.m. and 1:45 p.m. this week and next, as crews complete electrical work. It's part of Kapiolani Medical Center's expansion project.  Eastbound, the left lanes onto Punahou and onto Bingham Street from the H-1 freeway will be shut down. But, the right turn lanes will be open.  On the Westbound side, the onramp to the H-1 freeway from Punahou going west will be closed.  This work is expected to take about two weeks.
