Maryland Route 144 (MD 144) is a collection of state highways in the U.S. state of Maryland. These highways are sections of old alignment of U.S. Route 40 (US 40) between Cumberland and Baltimore. Along with US 40 Scenic, US 40 Alternate, and a few sections of county-maintained highway, MD 144 is assigned to what was once the main highway between the two cities, connecting those endpoints with Hancock, Hagerstown, Frederick, New Market, Mount Airy, Ellicott City, and Catonsville. MD 144 has seven disjoint sections of mainline highway that pass through mountainous areas of Allegany and Washington counties and the rolling piedmont of Frederick, Carroll, Howard, and Baltimore counties. ==Route description== There are seven mainline sections of MD 144: *MD 144 in Allegany County runs from MD 807 in Cumberland east to US 40 Scenic east of Flintstone. The state highway generally parallels I-68 and crosses over the freeway multiple times as both highways pass through mountainous creek valleys and over Martin Mountain and Polish Mountain.〔 *MD 144WB runs from I-68 west of Hancock to I-70 east of Hancock. The state highway was assigned in the mid-1960s following the completion of I-70 and the new alignment of US 40 on either side of Hancock.〔 *MD 144WA runs from US 40 west of Hagerstown to Western Maryland Parkway just west of the city limits of Hagerstown.〔 *MD 144FA runs from the intersection of Patrick Street and Jefferson Street in Frederick east to I-70 near Bartonsville.〔 *MD 144FB runs from the west town limit of New Market east to MD 75. This state-maintained segment of old US 40 lies between two county-maintained segments of the road in eastern Frederick County.〔 *MD 144A runs from MD 27 in Mount Airy east to US 40 in Ellicott City. The state highway briefly passes through Frederick and Carroll counties before serving as the main east–west surface highway of northern Howard County.〔 *MD 144 runs from the Howard–Baltimore county line at the Patapsco River east to US 1 in Baltimore. A county-maintained segment of Frederick Road continues west through Ellicott City to a junction with US 40 a short distance east of MD 144A.〔〔 MD 144 is a part of the National Highway System as a principal arterial in two sections. The first section runs from the western terminus of MD 144FA at Jefferson Street east to I-70 and US 40 within Frederick.〔〔 The second section runs from North Rolling Road in Catonsville to the highway's eastern terminus at US 1 in Baltimore.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Maryland Route 144」の詳細全文を読む スポンサード リンク
