Travel directions

State Route 17 along Lake Lenore in the Grand Coulee.

State Route 17 begins at Mesa on US 395. This is a branch off the major route from the Tri-Cities to Spokane. State Route 17 is a single-lane road through a generally sparsely populated area. The road leads through the easternmost part of the valley still irrigated from the Columbia River, with a lot of agriculture. Short to the east, however, are the steppes. The road does not pass through built-up areas between US 395 and the connection to Interstate 90.

North of I-90, State Route 17 forms a short 2×2 divided highway around Moses Lake. After that, the road is single lane again and often leads through desolate steppes. The height differences are not that big, but the road does lead through a canyon with lakes, this is called the Grand Coulee. It crosses US 2 at the Dry Falls Dam west of Coulee City. State Route 17 then continues north through barren rangeland to the Columbia River valley, which it crosses at Bridgeport. The road ends shortly afterwards at US 97 east of Brewster.

History

State Route 17 in the Grand Coulee.

The route did not form a historical connection, but originated from various gravel roads and newly constructed connections. Until the 1930s, almost the entire route was still unpaved. The section between Sims Corner and Bridgeport was only constructed in the 1950s. In 1951 the bridge opened over the Columbia River and State Route 17 was extended to US 97 at Brewster. The State Route 17 number was introduced with the major renumbering of state routes in 1964. Originally State Route 17 continued south to Eltopia but later became part of US 395 in the 1960s.. In the 1970s, the road between Mesa and Moses Lake was upgraded to an integrated north-south route, capable of faster speeds and shorter travel times. Between 1997 and 2007 the Moses Lake bypass was constructed as a 2×2 divided highway.

Every day, 5,000 to 8,000 vehicles drive between US 395 at Mesa and I-90 at Moses Lake. The Moses Lake bypass has 13,000 to 21,000 vehicles per day. This quickly drops to 3,000 to 2,000 vehicles per day as far as Coulee City and only 700 to 1,000 vehicles per day as far as Bridgeport. 2,500 vehicles a day travel between Bridgeport and Brewster.

State Route 18 or SR-18 is a state route in the U.S. state of Washington. Part highway, part highway, the road runs from Federal Way south of Seattle to Snoqualmie, east of Seattle, bypassing the metropolitan area of ​​Seattle from Tacoma toward the east of the state. The route is 46 kilometers long.

Travel directions

The highway begins in Federal Way, a suburb of 88,000 just south of Seattle. The road starts here with a cloverleaf at Interstate 5. With 2×3 lanes, the highway runs eastwards, crossing SR-167, the southeastern bypass of the metropolitan area. It then proceeds through a valley of industrial estates around Auburn, and the road then turns north-east in 2×2 lanes. You then pass through increasingly thinly built-up areas with quite a lot of forest. Just before Interstate 90, the road narrows to 1 lane in each direction and joins I-90 toward Spokane and Yakima.

History

State Route 18 was originally constructed between 1955 and 1964 as a two-lane highway connecting Tacoma to Snoqualmie Pass so that traffic did not have to travel through Seattle. In 1990, the highway ran only from Federal Way to Auburn, but has doubled to 2×2 lanes as of 1992 for much of the route northeast of Auburn.

Traffic intensities

The busiest point is at the beginning, between I-5 and SR-167 with 90,000 vehicles per day. This slowly drops to about 20,000 vehicles at the end of the road off I-90.

State Route 19 or SR-19 is a state route in the U.S. state of Washington. The road forms a north-south route on the Puget Sound, between Port Ludlow and Port Townsend. The road is 23 kilometers long.

Travel directions

State Route 19 begins south of Port Ludlow at an intersection with State Route 104. The road then heads north through the Beaver Valley, a hilly region close to the coast. The road runs outside Port Ludlow along and through the edge of Port Hadlock. The road then ends south of Port Townsend on State Route 20.

History

The road is a relatively new creation that only became part of Washington’s network of state highways in 1991. The road itself was built in the 1950s as a gravel road and was paved in the 1960s. This also explains why the road does not run through the historic city centers, but beyond. The road received state route status primarily because of the access to the small Jefferson County International Airport.

Traffic intensities

Every day, 6,000 vehicles drive on the southern part and 14,000 vehicles on the northern part.
