MD 400

Baltimore
Garrison

MD 400 · was Mt. Wilson La.
from MD 140 (Reisterstown Rd) west to former entrance of Mt Wilson State Hospital

Status: Decommissioned 1989, number no longer assigned.

Mt. Wilson State Hospital was closed in June 1981. Route 400 was dropped in 1989, 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 401

Baltimore
Butler

MD 401 · was Stringtown Rd.
2.13 mi.; from MD 25 (Falls Rd) northeast to intersection with Yeoho Rd & Cold Bottom Rd.

Status: Decommissioned 1985, number no longer assigned

With all the busy, unnumbered modern day roads in Hunt Valley connecting Falls Rd (25) and York Rd (45) with I-83 (Timonium, Padonia, Shawan, Belfast), the only numbered road in the area was this one, which goes no place in particular. The only numbered road to even cross I-83 south of Hereford, Seminary Ave (131), offers no connection to I-83 at all.

MD 404

Caroline
Hillsboro

Andersontown
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.

Status: Marked east-west.

NHS: All except small piece at western end, between US 50 and MD 213/662.

Associated Secret-Obscure Routes: 485

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 MD 404 went north from Matapeake along current MD 8, then east on MD 18 (which it superceded on maps; there was no dual 18/404 on any maps), and east on current US 50/MD 662 to the current western end at Wye Mills.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

Status: Part of route south of US 40 is now MD 755, number reassigned.

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.

Associated Secret-Obscure Routes: 884

Another Baltimore County spur, this one ending at the old railroad crossing in the town of Freeland. MD 409 was realigned slightly north at its intersection with MD 45 (York Road) in Maryland Line, to line up with the approach to I-83 Exit 37. Dropped in 1989 as part of the exchange that brought Security Blvd into the state system as MD 122.

MD 410 · Montgomery Ave, East-West Hwy, Burlington Ave, Philadelphia Ave [Takoma Park], Ethan Allen Ave [Takoma Park], East-West Hwy, Riverdale Rd, Veterans Pkwy
13.92 mi.; from MD 355 in Bethesda east to road end south of US 50 near Glenarden.

Status: 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.

In Prince George's County is a continued oddity, there remains a 0.35 mile gap in state maintenance east of the interchange with the Baltimore-Washington Parkway.

More breaks in state maintenance occur in Takoma Park, where SHA and the city are in talks to determine maintenance. According to SHA's HLR database, the maintenance transitions appear to be quite specific, down to 0.01 mile. But real property records were not well kept, and neither side can prove definitive ownership. There is no documentation to back up these maintenance claims, but they do serve as a starting point of any future movement on the matter. Mileages are from the beginning of 410 in Bethesda.

  • 4.56: Chicago Ave/Western Corp Limits
  • 4.56-5.00: SHA
  • 5.00: Chestnut Ave
  • 5.00-5.17: Takoma Park

  • 6.06: Elm Ave

  • 6.31: NH Ave (MD 650)/Eastern Corp Limits/PG-Mont Line

While this is being hammered out, SHA and Takoma Park have agreed to decouple the pending download of MD 787 (Flower Ave) to city maintenance.

MD 412

Prince George's
Riverdale
Edmonston
MD 412 · was Riverdale Rd
.

Status: Decommissioned 1990, number no longer assigned.

This route was likely dropped because it parallels modern MD 410, lying only a few blocks to the south. First there was a truncation between US 1 and Rhode Island Ave in 1974. The other part of Riverdale Road, MD 412A, from MD 201 west to Lafayette Ave, was dropped in 1990.

More info about 412 comes from Mark Cleveland:
MD 412 route was decommissioned, in two stages, when MD 410 was extended past U.S. 1 in Riverdale in the 1970s. MD 412 originally ran from US 1 via Queensbury Rd, across an at-grade crossing of the railroad, then jogging a block or two to the south to Riverdale Rd. and continued via Riverdale Rd. to MD 450, Annapolis Rd. Riverdale Rd. ended at that point. MD 410 was extended east from U.S. 1 in the 1970s as a four lane highway with a bridge across the railroad tracks to meet up with Riverdale Rd. a short distance east of the tracks. This bypass was essential to relieve heavy traffic on what were essentially residential streets and to eliminate the at-grade railroad crossing on what had become a major through traffic route. When (or, perhaps, shortly after) this extension was completed, Riverdale Rd. east of that point was renumbered as MD 410 to its end at MD 450. MD 412 was retained for a while (until at least the late 1970s) on its original routing from U.S. 1 through Riverdale via Queensbury Rd. and Riverdale Rd. up to the junction with MD 410. MD 410 was later extended east past MD 450, across yet another set of railroad (and Metrorail) tracks, to U.S. 50. I believe that this occurred in the 1980s.

MD 413 · Crisfield Hwy, Richardson Ave/Maryland Ave, W Main St
14.61 mi.; from US 13 southwest to road end in Crisfield.

Status: Marked north-south.

MD 413 is present in just about every map in which state route numbers are shown. I have no evidence that it was ever planned to be US 413. A new, straighter 413 was completed in 1950 alongside the abandoned rail alignment to Crisfield. The completed sections extended from Crisfield north to Hopewell in 1940 and to Marion by 1946. As new parts were opened, the old road would be assigned MD 667, which remains today, but the section north from Hudson's Corner was shifted eastward along old MD 406 to US 13.

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.
