State highway in Ohio, US

State Route 7 (SR 7), formerly known as Inter county Highway 7 until 1921 and State Highway 7 in 1922, is a north–south state highway in the southern and eastern portions of the U. S. state of Ohio. At about 336 mile (541 km) in length, it is the longest state route in Ohio. Its southern terminus is an interchange with U. S. Route 52 (US 52) just west of Chesapeake. Its northern terminus also serves as the eastern terminus of SR 531 in Conneaut. The path of SR 7 stays within 5 mile (8 km) of the Ohio River (Ohio's border with West Virginia) for the southern portion, with the river being visible from much of the route. The road also remains within 10 mile (16 km) of the Pennsylvania state line for the northern portion.

SR 7 starts in Chesapeake and runs along the Ohio River for about 235 mile (378 km). This portion of the highway encounters routes like US 35, US 33, US 50, and Interstate 77 (I 77). It passes through many Ohio River towns like Marietta, Bellaire, and Steubenville. Once it reaches the Pennsylvania border it heads north along SR 11 & US 30 from East Liverpool to Rogers. After it exits State Route 11 in Rogers the route turns north and starts tracking toward Youngstown. Upon reaching the junction with the Ohio Turnpike, OH SR 7 enters the Connecticut Western Reserve. Continuing north, it becomes Market Street in Boardman, Ohio, with a significant suburban increase. Then the highway heads east overlapped with US 62. After that shared alignment, the highway then heads north again in Hubbard through many small towns to its northern terminus with SR 531 in Conneaut.

The Chesapeake bypass was first proposed in 1953. In 1961, the US 52 expressway opened from Chesapeake westward towards Sheridan. The original eastern terminus of the four lane divided highway was at the current Chesapeake northbound only exit ramp east of Tallow Ridge Road. US 52 originally crossed at the present day Robert C. Byrd Bridge that connects Chesapeake to Huntington, West Virginia. In 1979, the US 52 designation moved to the Nick Joe Rahall II Bridge as tolls on that span were removed that year; the segment east of the Rahall Bridge to the Chesapeake interchange was renumbered to SR 7. Ten years later, the four lane expressway was extended eastward to an incomplete trumpet interchange just east of Big Branch Road. A four lane connector route from the partially complete interchange to the foot of the Robert C. Byrd Bridge at SR  527 was completed. At the same time, the two lane Chesapeake interchange ramp just east of Tallow Ridge Road was converted to a northbound only exit ramp. The abrupt terminus at Chesapeake was envisioned to connect to Proctorville. Though the portion of SR 527 is signed as part of SR 7, it is not officially part of the route and many signs show this portion of SR 527 as "To SR 7." On May 31, 2002, ground was broken for Phase 1 A of the Proctorville bypass. Phase 1 A entailed a two lane connector road from the East Huntington Bridge to Irene Road, with the original loop ramp from the bridge to State Route 7 being modified into an access road. Phase 1 B was designated from Irene Road to State Route 7 near Fairland East Elementary in Rome Township. Phase 2 was envisioned from Irene Road west to Chesapeake. The total cost was originally estimated to be at $165 million. The $6.5 million, The projected cost of the 4.5 mile (7 km) segment was originally $27 million, however, when the bids were let, the cost had decreased to $24.3 million. The lowest bid, which was also accepted, came in at $22.1 million. The road was designed as a two lane limited access facility on a four lane right of way. Construction began on August 4, with an original estimated completion date of June 30, 2005. An unusual amount of rain, blamed on two hurricanes, caused major delays. More than one dozen major slips along Phase 1 B required an additional $30 million in repairs and the purchase of additional land for highwall excavations. Another change was the design of the roadway; originally projected to be widened in the future when higher traffic counts warrant the expansion, it was designed on wide right of way with no grade separation between the opposing lanes. During the repair of the slips, a terraced roadway was constructed to separate the future southbound lanes from the northbound by a highwall when the roadway is expanded to four lanes. Other cost overruns had pushed the cost of construction to $62 million total, which included Phases 1 A and 1 B, up from the original estimates of $32 million. The primary cause was rapidly increasing land values and "unchecked zoning" along the project's projected right of way along with geo technical problems with rocky soil. The remainder, east to SR 7 near Fairland East Elementary, opened on December 8, 2006. It includes intersections with SR 775, Kinley Avenue, and SR 7. Upon completion, phases 1 A and 1 B were signed as SR 7; the bypass from the SR 775 junction to the loop at the East Huntington Bridge was co numbered with SR 775. Phase 2 of the bypass, from the Chesapeake bypass to Irene Road at Proctorville, has not been funded. Funding which had been previously promised by the Ohio Department of Transportation (ODOT) was later denied.

Business State Route 7 stretched from west of Middleport to about 4 mile (6 km) east of Pomeroy. The route followed the former alignment of State Route 7 that was replaced by the Pomeroy Bypass, and ran through the downtown areas of Middleport and Pomeroy. It joined with State Route 833 (the former alignment of U. S. Route 33) from 1 mile (2 km) west of Pomeroy to east of Pomeroy, including a brief concurrency with State Route 124, and then headed northeast to the eastern U. S. Route 33/State Route 7 interchange. The route was deleted between 2013 and 2015.
