MD 120 was east-west Waters Rd. before construction of current I-270 in the early 50s. It was broken in two, a shortened original western section and another further east on 118. The original 120 ran roughly along the path of Father Hurley Blvd. towards what is now I-270 Exit 16. The remaining western segment of Waters was shown as 120 along with the current road in a 1991 SHA grid map. Today, Aircraft Rd. is in sole possession of the 120 designation.

Email from Mark Stein:
As you stated, MD 120 was Waters Rd., which originally ran from MD 118 in "Old Germantown" (now Liberty Mill Rd.) to MD 355 just north of the old MD 355/27 split. When US 240/I70S/I270 was built, it got split in two. After the development of Germantown in the early 80s, it was split up even more. All that is left of Waters Rd. is a small segment to the north off of Liberty Mill Rd. (old MD 118) and a small segment to the west off of Wisteria Dr. When I was up there last weekend, however, I noticed that Aircraft Dr. from MD 118 north to Crystal Rock Dr. is signed MD 120 (If my memory serves me correctly, the road is signed North/South. The original road was signed East/West.) They are brand new signs."

Waters Rd. was unbroken before construction of current I-270 in the early 50s. Only a small western segment near 118 remains; the rest has been demolished for I-270 and other development.

The southern piece of this route was part of a broken 119 as well. Mileage total from the HLR includes the intervening county section between.

Update: The southern piece has been decommissioned this year.

Designated a state route around 1990, this six lane divided highway serves the Social Security Administration complex. Security is the final exit for I-70 before its inglorious end at a park and ride at the city line. Looking on the good side, a surface intersection with Ingleside Ave. is the last traffic light between here and Cove Fort, Utah...umm...Breezewood. It becomes unnumbered Cooks Lane to US 40 in Baltimore City, where there are still old "TO I-70N" shields alongside the traffic lights, put there by the city eons ago and forgotten.

Signage mistake: 'US' 124 just south of MD 115. This sign has since been corrected. (thanks to Mark Stein for photo)

MD 125 is a 'floating' route; it doesn't touch another route, though it once went further west to MD 99. Old Court Road continues as an unnumbered road northeast to Pikesville, where it becomes MD 133 for a few miles east to Ruxton, near I-83.

Route 125 begins Baltimore County's long numbering cluster, starting in the west, then north and southeast through the county, from 125 to 151 except 135-136.

Adjacent 0.92 mi. stretch of Gwynn Oak in Baltimore City led to MD 26, but not signed by the city. Near the other end at Windsor Mill, the route made an quick left turn from a 2-lane divided to continue on 126 and Gwynn Oak. Heading straight leads to unnumbered Woodlawn Ave. At least it ended up on Windsor Mill about 1000 feet west.

MD 129 runs northwest from Baltimore, and passes through some of the last open fields inside the Beltway. Contrary to what many computerized maps show, MD 129 does not extend south along Russell St. to I-95, although it would be a logical assumption. The part in question south of US 40 is officially part of MD 295, but there is no signage to this effect.

Sections of MD 132:
MD 132: W. Bel Air Ave. 2.15 mi.; from cul-de-sac east to APG Rd. The main section through downtown Aberdeen.
MD 132A: Beards Hill Rd. 0.24 mi.; connects MD 22 and Bel Air Ave. at western end near I-95.
MD 132B: Old Post Rd., Oakington Rd. 1.43 mi.; from MD 22 east to US 40. This section runs south of the railroad tracks. Part of the rest of Oakington was once MD 635.

This is the the same Old Court Rd. as in 125, but a segment several miles farther east.

MD 134 once also included Ruxton Rd. from the current northern terminus west to Falls Rd. (MD 25). At that time, the intersection of Ruxton and Falls Rd. was a little bit south of the current intersection, where it is even with Old Court Rd. (MD 133). Another case of staggered intersections getting different numbers.

A much different Pratt Street... MD 135 westbound, Luke. (picture 01/24/10)

You'd expect this one to be in northern Baltimore County, but not so, not even close. MD 135 breaks the clustering rules, even though it seems to have been around as long as all the other first-set routes. It's way out west in Allegany and Garrett Counties.

I have a theory as to why, though it's only conjecture. Possibly it had been part of MD 41, or possibly 46 for the shortest time early on (1930s or earlier), possibly to concur with WV 46. Another number that would have fit the pattern was 43; I haven't found an original route 43 or 46 yet out there, where they would have belonged.

Once ran along Swanton and Swanton Hill Rds., parts of which are now MD 495.

The portion between Westernport and Luke has to be seen to be believed. An active mill provides steam for the town of Luke which pours out of the gutters, followed by a near-vertical ledge overhanging several hundred feet above. MD 135 certainly warrants further exploration.

Sections of MD 135:
MD 135A: (no name) (AL) 0.78 mi.; from MD 135 north to US 220. Connector to US 220 in McCoole
MD 135B: Paxton St [McCoole] (AL) 0.11 mi.; also connects MD 135 and US 220.
MD 135C: (no name) (GA) 0.03 mi.; from MD 135 to salt dome entrance 1.4 miles east of MD 38.
MD 135D: Masteller Rd [Luke] (AL) 0.02 mi.; from MD 135 south to Potomac bridge/WV line. Becomes WV 46 on the other side.

Comprised of four roads: Calvary Rd. (MD 7 to MD 22), Priestford Rd. (MD 22 to US 1), Whiteford Rd. (US 1 to MD 624), and Harkins Rd. (MD 624 to MD 23). Makes a broad, semicircular swath through eastern and northern Harford County. Harkins between 23 and 24 was once MD 517. MD 136, at just over 30 miles, may be the longest intra-county state route. Not quite... MD 235 in St. Mary's Co. just beats out 136, 30.63 miles to 30.04.

There is a 0.4 mile break in state maintenance in unincorporated Monkton. In Hereford, at the western terminus with MD 45, two buildings are close in on either side of 138, making it look like just another street. Many folks miss the turn, especially because 137 (with its very visible intersection and access to I-83) is only 500 feet away on 45.

The primary north-south street in Baltimore, Charles shares the 139 designation with St. Paul St. in Baltimore City, one way northbound and southbound, respectively. North of Johns Hopkins University, Charles becomes two-way, continuing all the way out to I-695. The northern terminus consists of a roundabout with Bellona Ave. just past I-695.
