State Route 88 (SR 88) is a highway generally running in an east–west direction in the northeastern portion of the U.S. state of Ohio.
 Its southern terminus is in Portage County at Ohio State Route 59; at the intersection of Freedom Street with Main Street in Ravenna.
Route 88 is labeled north-south southwest of US 422 and Ohio 528, and labeled east-west east of US 422 and Ohio 528.
 Route 88 follows a northerly direction for a little more than a mile along Freedom Street, to the State Route 14 and State Route 44 concurrency bypass.
 From here, the route heads in a northeasterly direction.
 Its next intersection is with State Route 700, at the southern terminus of the latter route.
 A quarter mile further to the northeast, Route 88 joins State Route 303 for about a half mile.
 State Route 88 then continues northeast, crossing over Interstate 80 and The Ohio Turnpike, before turning due north as it enters Garrettsville.
 Here, as South Street, the route intersects with State Route 82 (State Street), then becomes North Street before exiting the corporation limits.
Route 17 is a state highway in Bergen County, New Jersey, United States, that provides a major route from the George Washington Bridge, Lincoln Tunnel and other northeast New Jersey points to the New York State Thruway at Suffern, New York.
 It runs 27.20 mi from Route 7/County Route 507 in North Arlington north to the New York border along Interstate 287 in Mahwah, where New York State Route 17 continues into New York.
 Between Route 7 and Route 3 in Rutherford, Route 17 serves as a local road.
 From Route 3 north to the junction with U.S. Route 46 in Hasbrouck Heights, the road is a suburban arterial with jughandles.
 The portion of Route 17, from US 46 to Interstate 287 near the state line in Mahwah, is a limited-access road with all cross traffic handled by interchanges, and many driveways and side streets accessed from right-in/right-out ramps from the right lane.
 For three miles (5 km) north of Route 4, well over a hundred retail stores and several large shopping malls line the route in the borough of Paramus.
 The remainder of this portion of Route 17 features lighter suburban development.
 The northernmost portion of Route 17 in Mahwah runs concurrent with Interstate 287 to the New York border.
Route 177 was the shortest state highway recorded in Somerset County, New Jersey and the second shortest around the entire state of New Jersey.

 One of only three state highways in Somerset County after the 1953 state highway renumbering, Route 177 was the only one to be decommissioned later on.
 (The other two highways are Route 27 further south and Route 28 further north) The short-lived designation went from U.S. Route 206 in Somerville, up Bridge Street near the Old Cemetery to Fifth Street, where state maintenance terminated.
 In 1974, the Department of Transportation turned maintenance of this short highway over to the borough of Somerville for future use.
