MDRoads.com is a guide to Maryland's highway system, past and present. Information is organized by type of highway (Interstate, US or state) and route number. This site is, and will probably always be, a work in progress; as time permits, I'll add maps, exit guides, and highway photos. In the meantime, here's the canonical list of Maryland highways, the text file from which sprang this entire site.

So what's here, you ask? Check out the links below:

Maryland's Interstates
Information on all Interstate highways in Maryland, including mileages, exits, and historical info.
Maryland's US Highways
All Maryland US Highways, current and those no longer around. Route 66 isn't the only extinct US highway; Maryland too has its fair share.
State Routes
Many of your favorites, or maybe not so favorites as the case may be, plus some others you may have never heard of. Also many unmarked routes and numbers which disappeared long ago. You may find you live along an unmarked or decommissioned route that carries a number or once did. There's also a list of unassigned numbers.
You can also jump straight to route pages using the pulldown menus to the left. Each Interstates and US highway has a page to itself. State pages are grouped with roughly twenty routes per page. See the legend page for more information.
Road Pics
Roadside photos from all over Maryland, arranged by county.

Maryland Highways in 1948
These maps I created based upon the official state map from 1948. They show some examples of the numbering clusters, 'broken' and 'floating' routes (each map will open in a new window):
Allegany   Anne Arundel   Baltimore   Calvert   Caroline   Carroll   Cecil   Charles   Dorchester   Frederick   Garrett   Harford   Howard   Kent   Montgomery   Prince George's   Queen Anne's   St. Mary's   Somerset   Talbot   Washington   Wicomico   Worcester
