The Big Island route list is in three tables:

Table 1 (preceding page) covers the current "Hawaii Belt" routes (routes 11, 19, and 190)

Table 2 (below) covers other routes (including old routes, some of which used to be part of the Hawaii Belt), numbered below 200

Table 3 (next page) covers all other routes (numbered routes 200 and above, and unnumbered highways)

(Actual county route shields are usually identical to state shields; see the FAQs for how routes are classified in the listings below.
Also, in many browsers letting your mouse linger over a route number graphic will help you decipher it.)

Former route (no longer in numbered state or county system)



Routes are generally listed in numerical order, with some exceptions to group portions of the same road with different names and/or numbers. For lists ordered differently (alphabetical by name, or by former route number):

JN State route 130 Keaau-Kalapana Road at end of pavement near Kaimu, southwest to parking area for trailhead to vantage points for viewing lava flows from the Kilauea volcano into the ocean; road built over part of route 130 right of way closed by lava flows; originally unpaved gravel road, except for four short surviving stretches of route 130 pavement (now road is completely paved); originally built in mid-2001, 2.6 miles long, to replace even rougher and longer road that had been access to what's left of the Royal Gardens subdivision; from August 2001 through April 2002, operated by Hawaii County as toll road to take tourists to safe lava viewing areas (until lava flows shifted well west of the road, into Hawaii Volcanoes National Park); toll was $5 for cars, $20 for commercial vehicles; closed to general public thereafter; westernmost < 0.4 mile severed by new lava flows in early March 2008, just before the flows reached the ocean; remainder of road reopened to general public March 8, 2008, for visitors to view the new lava flows into the ocean; tolls have not been re-imposed, though county officials may do so later; road shortened some more beginning March 12, 2008 by lava flows covering the westernmost remnant of old route 130 pavement; more lava started nibbling away at the westernmost remaining old route 130 pavement segment in May 2010 (by July 2010, lava overran former intersection of route 130 with county 137 within that segment), forcing the county government to once more relocate the lava viewing area and trailhead; as of October 2013, road shortened to about 0.8 mile, including only the two easternmost remnants of the original road (now used for trailhead parking), with a short hike from there to a lava viewing area ~ 0.8
miles
Road reopened to general public in March 2008, with limited hours, to visit lava viewing site. Other use of the road is RESTRICTED to residents and landowners in lava closure area, and perhaps also (assuming previous policy is resumed) native Hawaiians exercising hunting and fishing rights. Changed lava flows may close or further shorten road on short notice, or lead Hawaii County to re-close the road to the general public. See the Kilauea eruption update for the latest on lava flows in the closure area, and the Lava Closures photos pages for photos and other information.
Photos The part of the old access road continuing west of the new lava viewing trailhead, about three miles to the Royal Gardens subdivision, was re-covered by lava beginning in early 2001 and occasionally thereafter, and remains CLOSED indefinitely.

See listing above for former proposed Former state route 120, for apparently short-lived proposal in the early 1960s for a short state highway including this segment and also one looping back to south Hilo.

There is a gap of almost 20 miles between this western segment of route 137, and the eastern segment in the next listing. There are no firm plans to connect them with an auto road; indeed, the narrow Old Puna Road Trail that occupies much of the gap between the two segments may be improved, but restricted to non-motor-vehicle use.

A 1973 state highway map, and before then a 1961 Hawaii DOT planning document, indicates that there had been plans to construct a new road (which was to be part of at first state and then county route 137) to fill the gap, which may explain why the disconnected segments carry the same route number. In addition, a sign at JN County route 132, and mileposting of the eastern segment that places that junction at about mile 7.7 of route 137, suggests that there had been later plans to fill at least part of the gap, by improving a mostly rough, narrow, and unpaved road (4x4 recommended) from the Hawaiian Beaches Estates subdivision southeast to JN County route 132County route 137. (This road is neither signed nor milemarked, and is not currently county-maintained.)

A 2005 draft Hawaii County planning document, however, rejects a similar coastal route as an alternate route between Hilo and the Puna district, in part because its vulnerability to tsunamis and (at its eastern end) lava flows would make it a poor emergency evacuation route. Other inland routings, which would not connect the existing County route 137 segments, remain under consideration.

Hawaii County's official numbered route map does not include this or the following segment of County route 148. But they definitely are not in the state system (they were in 1960s, but a 1967 Hawaii DOT planning document targeted them for transfer to the county), and they are too well marked to be considered an "old" route. I have therefore treated them as a current county route.

miles

The county plans to extend Ali'i Drive south another 2.2 miles to JN State route 11 Mamalahoa Highway County route 160 Napoopoo Road. The last phase of right-of-way acquisition was underway as of November 2013.

In addition, the county has long planned to bypass the narrow northern part of this road, and part of State route 190 Palani Road, with a new 4.5-mile long Ali'i Parkway (originally was to be four lanes, now downsized to two). The plans approved in 2001 have been mired in controversy, especially after the discovery in the proposed right-of-way of native Hawaiian burial sites. In October 2007 the Hawaii Burial Council gave the go-ahead for construction to begin, with conditions to protect known and as-yet-undiscovered burial sites. The county expects the 300-feet-wide right-of-way, from when four lanes were planned, will leave enough room to build two lanes while minimizing issues with any additional sites that may be found. However, additional complications have placed the Ali'i Parkway project on indefinite hold.
