Starting on Sunday there will be schedule changes to more than a dozen TheBus routes on Oahu, and three routes will be discontinued altogether.

The city’s Department of Transportation said, in a news release Tuesday, that schedules are being modified “to limit service where there is little or no ridership, and routes with extremely low ridership will be discontinued,” and “service from underutilized routes can be reallocated to other communities/routes to best fit the needs of most of the riders.”

The discontinued routes include Route 80A (Hawaii Kai Park and Ride Express – University) Route 80B (Upper Aina Haina Express); and Route 235 (Kahala Mall — Waialae Iki).

The following routes will be modified:

>> Route 4 (Nuuanu – Punahou — McCully) will not loop around Kawananakoa Middle School. On their eastbound route, buses will travel from a new terminus fronting the Nuuanu Memorial Park and Mortuary, turn left on Wyllie Street, left on Liliha Street, left on Judd Street, right on Nuuanu Avenue and then resume the regular eastbound route. Westbound, buses will travel its normal route to Nuuanu Avenue and Kuakini Street before continuing mauka on Nuuanu Avenue to the Nuuanu Memorial Park and Mortuary terminus.

>> Route 13 (Liliha – Waikiki — University) will discontinue service on McCully Street in both directions. Buses will travel on the regular route to Kapiolani Boulevard and Kalakaua Avenue, turn right on Kalakaua Avenue and left on Kuhio Avenue before resuming on their regular route. Westbound, buses will travel their regular route to Kuhio Avenue, turn right on Kalakaua Avenue and left on Kapiolani Boulevard before resuming their regular westbound route.

>> Route 72 (Schofield – Wahiawa – Whitmore) will be split into two routes and renumbered with three-digit route numbers to identify their destinations as circulatory routes. They are Route 511 (Wahiawa — Schofield) and Route 512 (Waialua — Haleiwa). Route 511 will provide service between Wahiawa Transit Center and Schofield, and Route 512 will provide service between Wahiawa Transit Center and Whitmore.
