Installation of a traffic light at the main entrance to the University of Hawai'i-Hilo will start Jan. 19, with work from 7 a.m. to 5:30 p.m.

Improvements at the Kawili Street entrance site include a traffic light; left-turn, right-turn, acceleration and merge lanes; pedestrian crossings; and relocation of a drainage ditch.

"Kawili Street is a busy street on a curve," said UHH chancellor Rose Tseng in a news release. "Vehicles on the street have limited sight distance. Students who cross the street often have to run and dodge vehicles, some traveling over 40 mph. This is a safety concern for our students, and the traffic light has become critical for their protection."

Motorists are being advised to expect temporary traffic pattern changes and closures to the main entrance until the project's completion in September.
