Hawaii Highways road photos -- Introduction (page 2 of 2)

This is the second page of a introductory primer on the standard (and some of the non-standard) route markers and other road signs of Hawaii, and other roadside features found on all the islands.

The photos on page 1 focused on route signs and milemarkers. The photos below cover other kinds of signs, pavement markings, and other road features, and also contains links to the rest of the Hawaii Highways road photos pages.

NOTE: In case you want more detail, clicking a few of the photos below will call up enlarged, higher-quality (less .jpg compression) versions. Those alternate versions have larger file sizes, so please be patient while they download.

Page 1: non-Interstate route shields, milemarkers, etc.

Overhead signs on westbound H-1, approaching exit for northbound H-2
Standard route shields for the three main Interstate routes in Hawaii (all on Oahu). Hawaii's Interstate route numbers officially include a hyphen after the "H," but most shields posted on the freeways omit the hyphen (see below for some exceptions). (October and September 1999, respectively)

Overhead signs on eastbound H-201 with new Interstate shield, at exit 3 westbound H-3
Beginning in July 2004, Hawaii DOT started adding Interstate shields to the Moanalua Freeway, between H-1 exits 13 and 19, about a decade and a half after that segment was added to the Interstate system as Interstate H-201. The "bubble" shape of the Interstate shield blank, and the skinny characters, helped squeeze the four-character route number onto the shield, though at the expense of legibility. These photos were both taken just west of exit 3 on the eastbound freeway. (Both photos May 2005)

'To West H-1' marker, on shield painted on white background, with state name
Some of the signs currently on local streets directing traffic to the Interstates look like this, with hyphenated route numbers, and including the state name (as if it were ever necessary to remind people that they're in Hawaii!). Others look like the on-freeway shields shown above. (September 1999)
Name sign at west end of Interstate H-1, identifying it as Queen Liliuokalani Freeway
Most of Hawaii's Interstates were assigned only route numbers, and not route names (like all of Hawaii's other highways), until 2002. New signs like this (on eastbound H-1 at its west end) posting the new names include a hyphenated Interstate shield with the state name, but in a different style than shown above on local streets directing motorists to freeway entrances. These now are the only on-freeway Interstate shields with the state name, or with hyphenated route numbers. (February 2006, courtesy of Jeff Royston/AARoads.com)
Hawaii's Interstates have overhead signs, similar to those used in California, to give motorists advance notice of the next three exits. This sign is on westbound Interstate H-1 through downtown Honolulu at the Aala Street underpass, along with a low-clearance sign, and a 50mph maximum/40mph minimum speed limit sign typical on this older stretch of downtown freeway. (May 2005)
Overhead sign with distances to next three exits, along with 50mph/40mph speed limit sign, and 14ft6in low-clearance sign
60 mph speed limit sign on Interstate H-3
Hawaii was the last of the 50 states to hang on to the speed limit imposed by the old 55 mph National Maximum Speed Limit. In 2002, Hawaii DOT lightened up a little (a byproduct of public outcry over a short-lived photo speed enforcement program), posting a few stretches of freeway at 60 mph (none yet at 65 mph or higher), like this stretch of H-3 entering the Halawa Valley northeast toward the Koolau Range. (October 2004, courtesy of Ryan Ozawa)
This stretch of Interstate H-1 westbound through downtown Honolulu, from the Punahou overpass, displays typical pavement markings on Hawaii roads. There is extensive use of raised reflectors as supplemental lane markings, similar to California's old "Botts Dots" (it helps that only one or two ultra-high-altitude roads on the Big Island ever need snowplowing). On freeways, Hawaii DOT uses solid lines between lanes to keep motorists from moving from the left lanes into the right lane, where other traffic is about to enter it from the other side at a freeway entrance. (November 2001)
Lane markings on H-1 freeway, with raised reflectors between the travel lanes, and a solid line plus the raised reflectors between the center and right lanes approaching the on-ramp
State-maintained emergency callbox on route 93 in west Oahu Maui County-maintained emergency callbox on state route 340 in west Maui
Hawaii has emergency call boxes scattered along its Interstates and some other major routes. The call box signs resemble those in California.  The main difference is that while California's specify the county where the call box is located, Hawaii's instead show who maintains the call box ("State of Hawaii" if it's Hawaii DOT, as with the sign above left along state route 93 on Oahu, or "County of ___" for county-maintained boxes, as with the sign above right near the west end of state route 340 in northwest Maui). County-maintained call boxes also lack the code at the bottom indicating their location by route, traffic direction, and mile (times 10). (Both photos November 2001)
Hawaii DOT sticker on back of sign, indicating it is on state route 160, mile 3.64, and was placed April 1999
Hawaii DOT places on the back of some of its signs stickers like this one, to indicate exactly where the sign belongs, and when it was erected (in this case, on state route 160 on the Big Island, at mile 3.64, in April 1999). (January 2005, courtesy of Tim Reichard)
White gate sign: 'Kapu | 24 hr security' Rusted gate sign: 'Kapu | No Trespassing'
"Kapu" is Hawaiian for "forbidden." On a roadside sign, it means "no trespassing." (Both photos November 2001)
Hawaii Visitors Bureau warrior sign pointing to places of tourist interest, here pointing to the historic Kaupo Store in upcountry eastern Maui Evacuation route sign near Hilo waterfront, pointing right away from the shore; includes old-fashioned Civil Defense symbol
Hawaii Visitor Bureau signs like this highlight both major and minor places of interest along both state and county highways, as with this sign along an unpaved stretch of county route 31 south of the Haleakala volcano on Maui. (November 2001)
These "evacuation route" signs are particularly common in areas prone to tsunamis ("tidal waves"), as here near the Hilo waterfront. (November 2001)
Civil defense sirens, two banks of six horns pointing in opposite directions    Civil defense sirens A-F, two columns of three dark horns all facing forward    Civil defense siren, one horn in screened yellow enclosure pointing downward, with slanting deflector to direct sound outward    Civil defense sirens, a dozen yellow horns pointing outward in six different directions
Civil defense sirens of various types are particularly noticeable along the coasts of all the islands, for tsunami warnings, but are also a common sight along inland highways, particularly on the Big Island with its volcano and earthquake hazards.
