Hawaii

[The Ghostbuster]

It was always a "Fictional Highways" proposal. There is no way it would ever have been constructed. Another fictional proposal by kurumi was a westbound-only Interstate 338: http://kurumi.com/roads/3di/ix38.html#338ca. Since these fictitious proposals were made before the creation of the forum (which was launched in 2009), I do find them interesting.

Amusingly the Lahaina Bypass (HI 3000) has limited access elements and is going to be extended southward.  While unlikely it isn't totally unfeasible to envision the corridor eventually tied off closer to actual freeway standards. 

Likewise, HI 3800 does have a partial interchange with Kala Road and only one major at grade intersection with HI 36 east of Dairy Road/HI 380.  I could foresee a situation someday where it would be desirable to grade separate HI 3800 and HI 36. 

Interesting to note, HI 3800 is multiplexed along HI 380 to the junction of HI 3500/HI 311.  I assume that signage was placed given it gave traffic a single route to follow back to Kahului Airport.  My thought when I saw it was to truncate HI 380 just to Dairy Road and extend HI 3800 to HI 30.

I believe kurumi once suggested that an Interstate H-4 should be constructed on Maui: http://kurumi.com/roads/3di/ix01.html#201hi.

His proposal, "if my conscience ever evaporates", was to essentially freeway-ize the Hana Highway, "to enhance economic development in the Hana metro area" (c'mon, Hana is just a small town with pricey lodgings for rich tourists).

Perhaps out of an abundance of caution, a historic bridges district was established to protect the dozens of one-lane bridges on the highway. When an earthquake on the Big Island closed one of those bridges, it was replaced with a similarly narrow one-lane bridge (deck 13.2 feet wide, including a single 12-foot travel lane and two narrow shoulders).

Here is a SolarCatcher video of the I-H1.

Here is a profile of LikeLike Highway in Oahu.

H3 gets so much attention but you have stuff nearby like Likelike Highway (HI 63) and Pali Highway (HI 61) that gets slept on.  Pali Highway is the most scenic of the three IMO.

Tolls in Hawaii?

If passed, HDOT will make a section of the famous Hana Highway (from MP 31 to MP 40) into a TOLL ROAD!

[Plutonic Panda]

Obviously Hawaii will do something stupid.

Yup, and they have the authority to put tolls on the interstates in Oahu (if passed)...

[Rothman]

Tolls on I-H1 would be interesting.

[Max Rockatansky]

Always Piilani Highway if you need an alternate to Hana.  At least if there aren't any slides and you have the fortitude to deal with kinda questionable dirt road.

hopefully that's does not happen

Amusingly HI 92 is faster through downtown Honolulu during most weekdays.

Feed it.

It was malnourished and could have grown into H-4.

As folks know, I scan for headlines on California highways. While doing so this week, I ran across this:

https://www.mauinews.com/news/local-news/2025/01/state-proposes-new-route-for-west-maui-highway/

The state Department of Transportation has selected a preferred six-mile route in its pursuit of an alternative to the two-lane coastal Honoapiʻilani Highway in West Maui.

The proposed rerouting of a portion of the highway from Ukumehame to Launiupoko goes farther away from an ocean that has required the installation of concrete walls in certain places to fend off waves.

Flooding caused by high waves are regular occurrences on this low-lying highway, the state said.

Adraft environmental impact statement describing the alternate route as well as other proposed corridors is available for review at bit.ly/40nN8rN. Comments may be submitted through Feb. 24.

Under a state proposal, the jurisdiction of the existing coastal highway would be turned over to the county and eventually become a county road with opportunities to have public parks, beaches and open space consistent with the Pali to Puamana Parkway Master Plan. Each proposed alternate route assumes the existing highway would become a local access road.

[...]

As always, all together now, "Ready, set, discuss".

[The Ghostbuster]

Will this rerouting become a southern extension of HI 3000?

Will this rerouting become a southern extension of HI 3000?

I doubt it. The bypassed old HI 30 alignment is proposed to become a county road. That suggests HI 30 would be moved to the new road.

There would be some point to extending HI 3000 if the old alignment would remain part of the state highway system. ISTM the whole point of the project is to remove the flood-prone old alignment from the state system, and make it a local beach/shoreline access road.

New overpass signs/street labels are finally getting installed on the first 10 miles of the H1. Two weeks ago I already saw new labels being installed on the Aiea section between Red Hill and the Kaonohi overpass in the WB direction. Another one is going up as I post this in the Waiawa Overpass:

"Single lane closure on the H-1 Freeway, in the westbound direction, in the vicinity of the Waiawa Road Overpass, on the evening of Friday, March 28, through the morning of Saturday, March 29, from 8:30 p.m. to 4 a.m. for overpass sign work. " - https://hidot.hawaii.gov/highways/roadwork/oahu/

I couldn't get a picture yet, but they're pretty interesting. Not only are they going back to the mixed-case FHWA E series font, but they now use the diacritical markings (kahakō and ʻokina) as promised three years ago.

Speaking of which, when are they going to put up that westbound directional sign near the airport that they removed over a year ago?

[Short n Swift]

Found some new overpass signs near the Makakilo-Kalaeloa area:

I don't know about the rest of you, but the text on those signs looks a little ghastly to me.

it could be my camera, since I took the picture from a tinted car window

Finally, at last, Google is starting to roll out the 2024-25 street view maps on certain roads. I found this assembly that I alluded to in another thread, that used the same panel style (E/EM, centered "H1", state highway numbers closer to the bottom). Ironically, I prefer the Clearview assembly from 2011 or so, considering the spacing looks atrocious on the outer two signs, almost as if there were no spaces at all.
