Nevada State Route 400

State Route 400 (SR 400) is a state highway in central Pershing County, Nevada. It connects the rural town of Unionville to Mill City. The route originally extended further south under its prior designation as State Route 50.

Route description

The route starts at the beginning of pavement on Unionville Road, about 3 miles (4.8 km) east of the rural townsite of Unionville in Buena Vista Valley at Kyle Hot Springs Road. From there, SR 400 heads northward over Buena Vista Creek as it heads northward towards Coyote Ranch. The route parallels the Humboldt Range on its trek northward through the desert. The highway crosses over Star Creek and passes through the Dun Glen Flat as it heads into Mill City. State Route 400 comes to an end at the Mill City Interchange on Interstate 80 and U.S. Route 95.

History

The route's history begins as far back as 1933, when it appeared on official Nevada maps as a county road, diverging from old U.S. Route 40 beginning in Mill City and heading southerly past the current terminus through the town of Rochester, then westerly to reconnect to US 40. By 1935, the county road had been designated State Route 50 by the state. The route, as it existed in 1936, was an unpaved road approximately 42 miles (68 km) long. By 1941, SR 50 had been rerouted slightly to bypass Rochester to the north, connecting west to Oreana more directly and shaving 3 miles (4.8 km) miles of the route's length. The northern end of the route, composing the current limits of the highway, was paved by 1959.

Virginia State Route 400

State Route 400 (SR 400) is a primary state highway in the U.S. state of Virginia. Locally known as Washington Street, the state highway runs 1.79 miles (2.88 km) from the south city limit of the independent city of Alexandria north to 1st Street, still within Alexandria. SR 400 is a city street connection through Old Town Alexandria between the two segments of George Washington Memorial Parkway, one heading south toward Mount Vernon and one heading north toward Washington. The Virginia Department of Transportation assigned the unsigned SR 90005 designation to the two segments of the parkway and SR 400.

Route description

SR 400 begins at the south city limit of Alexandria at Hunting Creek. The highway continues south into Fairfax County and Belle Haven as the George Washington Memorial Parkway toward Mount Vernon. SR 400 is a four-lane divided highway through the Jones Point neighborhood before becoming undivided and crossing over the Capital Beltway (I-95 and I-495) on a freeway cap, a very wide overpass that shields the freeway from view of the crossing highway, between the Woodrow Wilson Bridge over the Potomac River and the Capital Beltway's interchange with U.S. Route 1 (US 1). The first intersection north of the bridge is with Church Street, which receives a ramp from the westbound Capital Beltway. SR 400 continues through Old Town Alexandria with six lanes and passes the Davis Chapel. The state highway meets the eastern ends of SR 236 (Duke Street) and SR 7 (King Street) in the Alexandria Historic District, where the Lyceum and Beulah Baptist Church line the southbound side of the street and the statue Appomattox lies in the middle of the street at its intersection with Prince Street. SR 400 continues north past the Christ Church, the Lloyd House, and the Lee-Fendall House to its northern terminus at 1st Street. George Washington Memorial Parkway resumes at this intersection and continues toward Arlington and Washington.
