Other notes-- Some
distinctive route markers (white-on-green, rather than the usual black-on-white), at the interchange between AK 3 and Trunk Rd. near Wasilla, suggest there is a Business Route 3 including frontage roads on both sides of AK 3. However, as discussed long ago elsewhere on the AARoads forum, the signs seems to be there to guide travelers to businesses on the AK 3 frontage roads, rather than to define a separate business route. In any case, there's no signage except on Trunk Rd. to confirm where the supposed business route extends or ends, such as where the frontage roads pass the Hyer Rd. interchange or end at the Seward Meridian Parkway. It does not appear on any official lists I've seen of numbered Alaska state highways, which also do not include any business or other bannered routes anywhere else in the state.
-- Many of the routes are concurrent in whole or in part with the existing Alaska Interstates route files, and I simply copied and spliced those files (minus deprecated labels). In particular, AK 3 = I-A4, AK 1 includes all of I-A3 and most of I-A1 (the west end of AK 1, south of Soldotna, is non-Interstate), AK 2 includes all of I-A2 and a small part of I-A1 (the west end of AK 2, west of Fairbanks, is non-Interstate), and a small part of AK 4 overlaps both AK 1 and I-A1. Any suggested fixes on those segments will need to be made to one or more other routes, too, so I'll be more reluctant to make such changes than for the non-Interstate routes.
-- AK 2 and AK 8 are milemarked east to west, and the waypoint order reflects that. AK 1 west of AK 9 is in reverse milemarker order, but the overall route is otherwise milemarked west to east, so I used that waypoint order for the entire route.
-- Since Alaska Marine Highway System terminals serve multiple vessels to multiple destinations, I labeled them all as "AMHSFry". That also distinguishes the AMHS ferry terminal on AK 7 (Petersburg) from the Rainforest Islands Ferry terminal at the other end of Mitkof Island.
-- Several waypoints on AK 11, AK 2, and AK 4 are labeled "PumpSta" followed by the station number. These are pump stations for the Trans-Alaska Pipeline, and are prominent facilities along those highways. (Pump Stations 1 and 8 are several miles off-highway, and Pump Station 11 was never built.) Their entrances are either right on the highway or at the end of short access roads. The state route logs name almost all of them "Pump Station _" whatever type of intersection applies.
-- There are lots of side roads, especially on AK 11, which are only pipeline service roads and are gated off. I ignored them all when I gathered GPS coordinates. A few pipeline service roads are open to the general public and serve non-pipeline destinations, and I included waypoints for them if they had names (other than "Pipeline Road __") in a state route log or online maps.
-- AK 7 (Juneau) includes a three-mile extension at its north end (old end was Echo Cove Rd.), which opened in 2013. Further extensions are possible, but are hugely controversial, ensnarled in environmental litigation, and in any event will not directly connect AK 7 (Juneau) to AK 7 (Haines), AK 98, or any other state highway -- at best, the extended road will lead to a new ferry terminal, reducing travel times by shortening the ferry connections to Haines and Skagway.
--- AK 10 has a long unbuilt portion between Chitina and the Million Dollar Bridge east of Cordova, with no connection between the two segments. Alaska DOT&PF had planned to convert an old railroad track bed into an auto road link, but the track bed was severely damaged in a 1964 earthquake, and the plans to connect the two AK 10 segments haven't really recovered from that. As previously noted, there is intense opposition in Cordova to completing those plans.
-- The SumLake point on AK 4 is for the community of Summit Lake, not the adjacent lake of the same name. The community has a small street network with several homes and other buildings on it, but the streets appear to be unnamed. Summit Lake is best known, and most visited, for the annual Arctic Man winter sports competition there, drawing thousands of participants and spectators from all over Alaska.
-- AK 4 has two other waypoints labeled for place names, Pta(rmigan) and Wor(tmanns). Unlike Summit Lake, there aren't any real communities at those places, just two homes off the side of the highway at each place.
