MD 81 · was Sabillasville Rd.
old number for MD 550 north of Thurmont.

No longer assigned (decommissioned 1977); entire route now part of MD 550.

Still numbered 81 until 1977, MD 550 was extended through Thurmont onto this portion, which runs north to Blue Ridge Summit and Pen Mar. It was a bit close to I-81, but didn't have an exit on I-70, like MD 68 and I-68 do 18 miles apart.

MD 83 · was Church St [New Windsor]
one block south of Main St. (MD 31).

No longer assigned (decommissioned).

Only reference to MD 83 is in a 30s or 40s SRC operating budget.

We now move east to Carroll County, which holds sway with Routes 83-93 except 92; 4 of these 10 remain as they were (84, 86, 88, 91). Route 92 breaks the rule by being back west in Washington County. The rest, seemingly important numbers all (83, 85, 87, 89, 90, 93), are now quiet country roads with no hint of their numbered past. There are plenty more obscure deleted Carroll routes in store up in the 500s and 600s ranges.

Comprises the old US 15 south of Frederick before it was rerouted along part of limited-access US 15-340, then south for a more direct link to its Potomac crossing into Virginia at Point of Rocks.

A new SPUI interchange with I-70 was completed in 2009, replacing the previous interchange with MD 355. MD 85 now ends at Monocacy Blvd, still under construction, and becomes the extension of East Street (unsigned MD 475) north into Frederick.

No longer assigned (decommissioned 1956).

A 0.4 mi. portion between 482 and 27 is now unsigned MD 849. Before a recent repaving, you could see remains of a narrower concrete slab which ended with the route, where Leister's Church changes names to Dutrow Rd.

MD 87,89,90 - E Carroll Co. MD 87, 89 & 90 in eastern Carroll County shown on 1954 Esso map. Red line was US 140 (now MD 140 & MD 97). Route 31 shown on the map is now 27. MD 87 ended near where it hits the 's' in 'Westminster'. MD 89 ended at the county line, consisting only of the section pointed to on the map. The road southeast of Hampstead is MD 88; the marker is cropped off the right edge of the map. As can be seen here, taking 90 didn't get you to O.C. back then. :) It ended at an indeterminate point between the 90 marker and the lettering for 'Carrollton' on the map.

Marked east-west.

MD 88 is a useful route for getting around the congestion of MD 30/140 and I-795. It dumps you into MD 25 (Falls Rd), the only drawback comes if you have to get to I-83. In that case. Lower Beckleysville Rd (former MD 89) gives access to MD 137 which connects direcly to I-83.

MD 89 · was Lower Beckleysville Rd.
from MD 88 northeast to Carroll-Baltimore county line.

No longer assigned (decommissioned 1956).

In a classic piece of Maryland route strangeness, MD 89 ended at the Carroll/Batlimore county line. Lower Beckleysville continued east to MD 25, in the process MD 137 ended here. The intersection with MD 88 is now a circle, and this road is marked "TO MD 137". Google Maps currently has this incorrectly depicted as being part of 137. Great idea, but it hasn't happened yet. If it's so important, either extend 137 west, or bring back 89, but for all of Lower Beckleysville east to MD 25. Of course, Baltimore County would have to give up lane-miles in more central areas to achieve this.

MD 90 · Ocean City Expwy.
11.83 mi.; from US 50 east to MD 528.

Marked east-west.

NHS: Entire length

Completed in 1971 as an alternative to US 50, MD 90 offers a second bridge across the Isle of Wight and Assawoman Bays into Ocean City. Hits MD 528 at 62nd Street. Although an 'expressway', 90 has one at-grade intersection with a traffic light. This is at St. Martin's Neck Rd., where the round trip without this junction amounts to 15 miles.

A 2-lane partially divided, controlled access highway, 90 is one of the more dangerous roads in Maryland. Its straightness can lull you into a false sense of confidence, and the approaching scenery of Ocean City can distract you. Add a beach traffic backup ahead just beyond the limited sight distance, and conditions are ripe for frequent accidents. Center dividers are being installed to prevent head-on collisions, and signs warning about possible sudden traffic backups have been added. Daytime headlights are required, as on the adjacent 2-lane parts of US 113.

No longer assigned (decommissioned 1956).

Now opposite the new alignment of MD 88. The endpoint of the old route, from my best guess on old maps, was near St Pauls Rd. See the map under MD 87 above for an idea of the layout here.

Sunset on former MD 90Scenes like this make all these roadtrips worthwhile. Taken 07/12/09 from former MD 90.

MD 93 · was Oakland Rd.

No longer assigned (decommissioned 1954).

Dropped in mid-fifties when Liberty Reservoir took out its bridge over the Patapsco River. It marks the end of Carroll County's initial 83-93 numbering cluster. Howard County is home to 94-106.

MD 93 - SE Carroll Co.MD 93 shown on a 1954 Esso General Drafting map. The river running north-south is the Patapsco River's northern branch, forming the Carroll-Baltimore county line. A dam was later built, creating Liberty Reservoir, eliminating the 93 bridge across the river at Oakland. MD 93 was soon scrapped.

55.27 mi.; from US 29/MD 384 in Silver Spring north to PA line.

Marked north-south.

Once ended short of Howard-Carroll county line., later taking over alignment of old MD 570 to Westminster. MD 97 traversed the current MD 140 west through Taneytown to Emmitsburg before US 140 was decommissioned in 1979. At that time 140 and 97 swapped alignments, making both routes straighter.

Named Georgia Ave throughout Montgomery Co, Roxbury Mills/Hoods Mill Rd in Howard Co, Old/New Washington Rd south of Westminster, Malcolm Dr in Westminster near the eastern split with 140, Baltimore Blvd along the 97-140 concurrency, and Littlestown Pike from the western 140 split north to the PA border.

Much further south, and in another world completely from Carroll and western Howard, in Montgomery County (down in Silver Spring) the route for a brief time ended at MD 390, as if it may have planned to be shifted onto the latter. There was once an 'End State Maintenance' sign at this point. However, that section has since been restored to state maintenance, with signage confirmed by multiple readers.
