The following highways are numbered 91:
Route 91 is a bus route operated by the Maryland Transit Administration in Baltimore. The line currently runs from Sinai Hospital to City Hall, serving the communities of Pimlico, Arlington, Walbrook, and Bolton Hill, Coppin State College and the corridors of Garrison Boulevard and Eutaw Place. The line has the second-highest farebox recovery rate of all MTA bus lines.
The bus route is the successor to the 16 Madison Avenue and 31 Garrison Boulevard streetcar lines.
Route 91 started operating in 1987 after being split from the long Route 19. It has followed essentially the same route throughout its lifetime since then, only with the modification of service operating via the Rogers Avenue Metro Subway Station full-time. The line has faced various proposals for consolidation into other lines, but all have been fought.
The No. 31 Streetcar started operating in 1917. In 1952, it was absorbed by the No. 19 Streetcar, which in 1956 was converted to a bus. The no. 19 bus continued to operate from the Harford Road corridor to Garrison Boulevard for more than 30 years. The route was extended to Sinai Hospital when it absorbed the short lived Bus Route 90, which had operated from 1959 to 1960 between the Belvedere loop to Sinai.
Route 91 is a numbered State Highway running 12.0 miles (19.3 km) in Rhode Island.
Route 91 begins at an intersection with Route 3 (High Street) in the town of Westerly, Rhode Island. Route 91 proceeds eastbound along Oak Street as a two-lane commercial street through Westerly, paralleling the Amtrak Northeast Corridor. In the easternmost extremities of Westerly, the road enters a partial cloverleaf interchange with Route 78 (Westerly Bypass) exit 5. After Route 78, Route 91 changes to Westerly–Bradford Road. The route turns southeast, away from the Northeast Corridor and crosses through flat lands east of Westerly.
Crossing over swampland, Route 91 intersects with Bradford Road, where it turns north along Bradford. The road crosses through some small communities in Westerly, returning to a parallel with the Northeast Corridor. Entering a small commercial center in the town of Westerly, Route 91 continues northeast as Bradford Road and intersects with Route 216. Route 91 and Route 216 proceed north along a concurrency, crossing over the Northeast Corridor. Paralleling the Pawcatuck River, Routes 91 and 216 leave the town of Westerly for the town of Hopkinton.
State highways in Kentucky are maintained by the Kentucky Transportation Cabinet, which classifies routes as either primary or secondary. Some routes, such as Kentucky Route 80, are both primary and secondary, with only a segment of the route listed as part of the primary system. Despite the name, there is no difference in signage between primary and secondary routes.
Due to the large size of the state highway system, only segments of routes that are part of the primary system are listed below. Complete lists are on the following pages:
All of the Interstates and parkways are also primary, but only parts of the U.S. Highways in Kentucky are (though every mainline U.S. Highway is at least partially primary).
Kentucky Route 949 (KY 949) is a rural secondary east–west state highway in west-central Kentucky.
KY 949's western terminus is located just north of Dunmor at a junction with U.S. Route 431 (US 431) in southeastern Muhlenberg County. It winds and curves its way through Gus, crosses the Mud River into Butler County and ends at an intersection on KY 06 just south of Huntsville.
It serves a direct link from western Butler County to the Lake Malone area.
Kentucky Route 1352 (KY 1352) is a north–south, rural, secondary state highway that is located entirely in Edmonson County in west-central Kentucky. It is known locally as Stockholm Road, which is 1.684 miles (2.710 km) long.
KY 1352 originates at the northern park boundary of Mammoth Cave National Park near an intersection with Little Jordan Road. The highway runs for almost 1 2⁄3 miles (2.7 km), and KY 1352 ends at a junction with KY 1827 at Stockholm.
Kentucky Route 91 (KY 91) is a 49.783-mile (80.118 km) state highway that traverses three counties in western Kentucky. It begins in Hopkinsville, Kentucky and ends at the Ohio River, the Kentucky-Illinois state line in northern Crittenden County.
It begins at a junction with US Route 68 and Kentucky Route 80 in Hopkinsville, Kentucky, the Christian County seat. It crosses KY-1682, the Hopkinsville By-Pass before leaving town. It goes on a northwesterly path, and its junction with Kentucky Route 398 is KY 91's access point to Pennyrile Forest State Resort Park.
KY 91 enters Caldwell County, and then it would meet Kentucky Routes 139 and 293, along with US Route 62 in downtown Princeton. It then traverses the Wendell H. Ford Western Kentucky Parkway (a part of the future routing of Interstate 69 in western Kentucky) on the northwest outskirts of Princeton.
KY 91 meets Kentucky Route 70 and then US Route 641 at Fredonia, a community northwest of Princeton. KY 70, KY 91, and US 641 would run concurrently from there into Crittenden County. KY 70 departs from US 641/KY 91 at a point north of the Crittenden-Caldwell County line, while KY 91 remains with US 641 until the U.S. Route's northern terminus at the US Route 60 junction at Kentucky. For a few blocks, KY 91 runs concurrently with US 60, and then KY 91 goes further north to reach its northern terminus at the Cave-In-Rock Ferry on the Ohio River, which will mark the Kentucky-Illinois state line. It becomes Illinois State Highway 1 upon entry into Hardin County, Illinois.
