Ohio State Route 2

State Route 2 (SR 2), formerly known as Inter-county Highway 2 until 1921 and State Highway 2 in 1922, is an east–west highway crossing most of northern Ohio and the fourth longest state route. Its western terminus is at the Indiana state line near Hicksville where the route becomes Indiana State Road 37 which continues to Fort Wayne, Indiana. The eastern terminus of the route is in Painesville Township in Lake County at U.S. Route 20 (US 20).

It passes through Bryan, Wauseon (where it briefly becomes a couplet), and enters greater Toledo west of its interchange with the Ohio Turnpike. It continues east from greater Toledo and soon parallels Lake Erie, becoming a freeway near Port Clinton. From Oregon to Sandusky SR 2 is part of 293 miles (472 km) of the highway designated the "Lake Erie Coastal Ohio Trail". and on September 22, 2005, was designated a National Scenic Byway. From Toledo to Sandusky the highway is also part of and designated the Lake Erie Circle Tour that is also part of the 6,500-mile (10,500 km) "Great Lakes Circle Tour". It then passes Sandusky, where it meets U.S. Route 250 (US 250) and US 6, and separates from the lakeshore as a freeway, and traverses rural Erie County before entering Lorain County. Near Elyria, it joins Interstate 90 (I-90), whose route it shares to Rocky River, where it follows SR 254 along Detroit Road into Lakewood. Here it again joins US 6, as well as US 20 on Clifton Boulevard. It then becomes part of the Cleveland Memorial Shoreway in Cleveland, joining I-90 again near Burke Lakefront Airport. These two highways split near Euclid, and SR 2 continues along the Lakeland Freeway to Painesville, feeding into US 20 eastbound. SR 2 serves as an access route to lakeshore attractions on Lake Erie from Toledo and Cleveland and as an alternative to the Ohio Turnpike.

The stretch of SR 2 from Toledo to Sandusky passes several attractions. The Ottawa National Wildlife Refuge is just east of SR 19 in Carroll Township. It sits on 733 acres (297 ha) along with the Davis–Besse Nuclear Power Station.

While Ohio state-numbered routes within cities are usually maintained by those cities (see Numbered highways in Ohio), SR 2 within the cities in the section in Lake County is maintained by the county.

SR 2 is the lowest numbered state route in Ohio. The SR 1 designation was removed in 1965.

The Cleveland Memorial Shoreway, often shortened to "the Shoreway", is a limited-access freeway in Cleveland and Bratenahl. It closely follows the shore of Lake Erie and connects the east and west sides of Cleveland via the Main Avenue Bridge over the Cuyahoga River. The entire length of the Shoreway is part of SR 2 and the Lake Erie Circle Tour; the Shoreway also carries parts of I-90 and SR 283 on its eastern side and parts of US 6 and US 20 on its western side. The Cleveland neighborhood of Detroit-Shoreway is named after the two roads that form the northern border, the Shoreway and Detroit Avenue.

The Shoreway was originally constructed in 1936 under the Works Progress Administration (WPA) and was extended in both directions during the 1930s and 1940s, finally completed and widened in 1953. Later in the 1950s, it was connected with additional freeways. It was named in honor of the city's war veterans during World War II. Between 2014 and 2018, the West Shoreway, the portion of the Shoreway from the Cuyahoga River westward, was reconstructed in order to increase ease of access to Lake Erie; the project included a speed limit reduction and various other feature modifications, though not as many as originally planned. Since the reconstruction, this section is also called Edgewater Parkway, and was also given the honorary designation "Governor Richard F. Celeste Shoreway" in 2016.

The Lakeland Freeway links Cleveland and Cuyahoga County to the suburban areas of Lake County. It begins at the east end of the Cleveland Memorial Shoreway and passes through the municipalities of Euclid, where I-90 diverges from SR 2; Wickliffe; Willowick; Willoughby; Eastlake; Mentor; Painesville; and Painesville Township. The freeway was extensively rebuilt in Lake County west of SR 44 between 2006 and 2012, which included the extension of one lane in each direction between SR 640 and SR 44. The Lake County section of freeway was authorized by Lake County Commissioners in 1957, and constructed and opened to traffic in the early 1960s. It was blended into the Cleveland Memorial Shoreway at the western end in Cuyahoga County, roughly as planned in 1944; because of that, the "Shoreway" name is often applied to the Lakeland Freeway from its west end to the I-90/SR 2 interchange.
