State Road Inventories

How many state DOT's have these online? I'm currently looking at MA's and it's very extensive.

WSDOT in Washington has a route log and SRWeb, which is like their version of GMSV integrated with the route log.

I believe ODOT in Oregon has something similar as well.

The way MA has it, every single road and bike path for that matter has a #. The "N" routes are what I'm currently 'digesting.'

West Virginia posts a complete listing of Interstate, U.S. Routes, State Routes and LSRs in its "Control and Intermediate Destinations" listing, which can be found as appendices to several larger process manuals online.  This one comes as Appendix B to the Design Guide for Signage published in January 2017 and is the most up-to-date that I can find.  https://transportation.wv.gov/highways/engineering/Documents/Publications%20Committee%20Meeting/DGFS%20-%20FINAL%2002.08.17.pdf

The DOH has problems with its configuration management on this document.  It still shows a date of 2015, even though this version shows one revision since then.  If I recall correctly, there was also a previous version listed as TED 220-2 (revision #2).  If you aren't careful searching with Google or directly, you will find the original version from 1993 (TED 220) or a reference the version 2006 (TED 220-1), which I can no longer find.  The linkpage for all of the Transportation Engineering Directives still points to the 1993 version.  Ouch.

Maryland has a comprehensive list of roads that are maintained by the two state agencies that own and maintain most of the "important" roads (counties and municipalities also have their own road networks):

MDOT/SHA (responsible for nearly everything with a public route number of any kind except in Baltimore City); and
MDTA (responsible for nearly everything in Maryland that charges a toll, save for a toll ferry on the Potomac River near Leesburg, Virginia and a low-water toll bridge on the North Branch of the Potomac River between Green Spring, West Virginia and Oldtown, Maryland).

The list of Maryland's state-maintained roads is called the Highway Location Reference, is organized by county (one volume per county) and route number, Interstates first. 

It can be found online here.

In Virginia, VDOT has a comprehensive traffic count book for its primary system roads (generally route numbers less than or equal to 599) across the Commonwealth that can be found here.

INDOT has not posted an update to theirs since 2016.
