A Change in Format

Since 1997, the Route Listings on this website have consisted of multiple routes (sometimes more than a dozen) per listings page. For example, the Routes 120–139 page not only contained complete details on 13 different state trunkline routes, but included listings for US-127 and US-131, each of which were quite lengthy in their own rights! With more information being added to many of the listings, including "new" historical data, it became clear there was no longer a benefit to breaking down the listings into "ranges" as had been done for the first 16 years of this website's existence. As such, the long process of separating each listing out into its own page commenced in May 2013. Separate pages for each former state trunkline highway route as well (e.g. Former M-4) are also being planned, but the information for those pages will come online once all of the existing (and "recently-existing") route listings have been migrated to the new single-route format.

This process will take some time, however, so your patience is appreciated! The 24 range-based route listings pages—like this page—will remain online indefinitely to provide easy links to each individual route listing, especially helpful for those accessing the site via older links which have not yet been updated to point to the new single-route listing.

As always, your feedback, suggestions and corrections are always appreciated!
