MD 400
· was Mt. Wilson La.

No longer assigned (decommissioned 1986). Mt. Wilson State Hospital was closed in June 1981. Route 400 was dropped in 1986, with signage lasting a few years longer. Like 325 and 479, other entrances to former state mental hospitals, when these institutions were closed and the land sold to other interests, the route numbers were dropped. |

MD 404
· Queen Anne's Hwy, Shore Hwy
24.61 mi.; from MD 213/662 in Wye Mills east to Delaware state line east of Andersontown.
Marked east-west. NHS: All except small piece at western end, between US 50 and MD 213/662. A long-time main drag on the Eastern Shore, and an alternate to US 50 in reaching the ocean, particularly the Delaware resorts. MD 404 goes back to the beginning of the numbering system. Before the completion of the Bay Bridge, 404 extended all the way across the Bay to what is now the US 50/301-MD 2/450 interchange (Exit 27). A ferry went between Sandy Point (roughly where the Bay Bridge toll plaza is today) and Matapeake on the western shore of Kent Island. MD 404 went north from Matapeake along current MD 8, then east on MD 18 (which it superceded on maps; there was no dual 18/404 on any maps), and east on current US 50/MD 662 to the current western end at Wye Mills. MD 404 also forms the Talbot-Queen Anne's county line and near Andersontown is home to the only instance of three concurrent state routes: 404, 16 and 313. East of Wye Mills, 404 ran through Queen Anne and Hillsboro before reaching Denton. A busy, flat and straight 2-lane highway, 404 in recent years has experienced many serious accidents, averaging 72 per year from 1995-99, and 46 fatalities in the last 20 years.

MD 408
· was Edgewood Rd
from MD 7 south to APG Edgewood Area gate.
No longer assigned (decommissioned), part of route is now MD 755. MD 408 was likely changed to 755 at the same time as the arrival of the current 408 in southern Anne Arundel Co. MD 24 once had its southern end at MD 7, and 408 was the main road extending south. MD 24 now bypasses this whole road. The part of 408 between MD 7 and US 40, which includes a one-lane railroad underpass, was recently dropped as part of 755. ................... |

13.92 mi.; from MD 355 in Bethesda east to road end south of US 50 near Glenarden.
Marked east-west. The sections of MD 410 near Silver Spring were completed in 1932-33 (it's unknown whether it got the 410 number that early too). By 1951, 410 had taken over old MD 209 (Ager Rd.) to MD 500, running east on Hamilton St to 40th Ave. |

No longer assigned (decommissioned), entire route now part of MD 4. Prior to MD 4 being extended southward along Southern Maryland Blvd, 4 went east along what is now MD 408, ending at MD 2. SM Blvd between 4 and 2 was originally MD 416. Later it was extended south along MD 2 for the length of Calvert County, creating a long 2/416 dual signage. MD 416 disappeared when MD 4 took over its entire length, the old 4 becoming 408, and the long dual route 2/4. ................... |
