State Route 503 (SR 503) is a 54.11-mile-long (87.08 km) state highway serving Clark and Cowlitz counties in the U.S. state of Washington. The highway travels north from a short concurrency with SR 500 in Orchards through Battle Ground, the eastern terminus of SR 502, and communities in rural Clark County before crossing the Lewis River on the Yale Bridge. SR 503 intersects its spur route and turns west to parallel the Lewis River downstream to Woodland, where the highway ends at an interchange with Interstate 5 (I-5). The highway was part of the Lewis River Road, signed as State Road 15, from 1909 until 1919. The current route of SR 503 was split between Secondary State Highway 1S (SSH 1) from Woodland to Battle Ground and SSH 1U from Battle Ground to Orchards in 1937, combined to form SR 503 during the 1964 highway renumbering. A spur route, established in 1991, travels northeast into the Gifford Pinchot National Forest along Yale Lake, serving the community of Cougar.
State Route 432 (SR 432) is a 10.32-mile-long (16.61 km) state highway in the U.S. state of Washington, serving the cities of Longview and Kelso in Cowlitz County. The highway travels east along the Columbia River from an intersection with SR 4 in West Longview through the Port of Longview and the termini of SR 433 and SR 411 in Longview. SR 432 crosses the Cowlitz River on a divided highway and ends at an interchange with Interstate 5 (I-5) in Kelso. SR 432 was established during the 1964 highway renumbering as SR 832, replacing a branch of Primary State Highway 12 (PSH 12) that had been routed through Longview and Kelso since 1937. SR 432 was established in 1968 and originally routed on Nichols Boulevard within Longview and was re-aligned onto its current route in 1991 after the opening of Industrial Way.
U.S. Route 12 is a major east–west U.S. Highway, running from Aberdeen, Washington, to Detroit, Michigan. It spans 430.8 miles (693.3 km) across the state of Washington, making it the second longest highway in the state. It is also the only numbered highway to span the entire state from west to east, starting near the Pacific Ocean, and crossing the Idaho state line near Clarkston. It crosses the Cascade Range over White Pass, south of Mount Rainier National Park. Portions of it are concurrent with Interstate 5 (I-5) and Interstate 82 (I-82), although the majority of the route does not parallel any interstate highway.
State Route 433 is a 0.94-mile (1.51 km) long state highway located entirely in Cowlitz County, Washington, United States. The highway begins midway across the Columbia River on the National Register of Historic Places listed Lewis and Clark Bridge and travels north to SR 432 in Longview. Prior to the 1964 state highway renumbering the highway was part of Primary State Highway 12. Between 1964 and 1972, the highway's designation was changed from State Route 833 to the current SR 433.

The Nutty Narrows Bridge is a squirrel bridge in Longview, Washington, United States. It spans Olympia Way near R. A. Long Park in downtown Longview, comprising a 60 feet (18 m) catenary bridge with a center section resembling a suspension bridge. The bridge was built by local contractor Amos Peters in 1963 and named by a city councilwoman, in a likely nod to the Tacoma Narrows Bridge.
The Yale Bridge or Lewis River Bridge spans the Lewis River near Yale, Washington. It was built in 1932 by Cowlitz and Clark counties. The suspension bridge has a clear span of 300 feet (91 m), with a total length of 532 feet (162 m), replacing a previous steel truss bridge at the site. Construction of the Ariel Dam had created Lake Merwin with a water depth of 90 feet (27 m) at the site, requiring a new bridge that did not need to have support piers in the water. The road deck, stiffened by a steel Warren truss, is 50 feet (15 m) above the high water line of the reservoir.
