Washington State Route 433

On Monday, October 3, 2016, in the middle of a good rain, we crossed half of the Columbia River on Washington State Route 433.

RCW 47.17.630
State route No. 433:

A state highway to be known as state route number 433 is established as follows:

Beginning at the Washington-Oregon boundary on the interstate bridge at Longview, thence northerly to a junction with state route number 432 in Longview.

This recently re-painted bridge over the Columbia River opened in 1930 as a private toll road, but was sold to the state in 1947. In 1964, the route was numbered SR 833, a child of US Route 830, but in 1968, US 830 became SR 4, so SR 833 became SR 433. Makes sense, no? So here, in the middle of the middle span, we enter Washington and begin SR 433.


Oversize load coming toward us. A bicyclist with a trailer going our direction. A few swishes of the wiper blades later, heading down the trestle, we reach the halfway point of SR 433. With no intermediate junctions on this route, here's a photo of the midpoint.


At the bottom of the trestle, between the lumberyard and the railroad, we arrive at the end of SR 433 and the junction with SR 432. Our route used to continue another mile north, but SR 432 was moved, so SR 433 was shortened. Such is life.

What's not to like about crossing a narrow, high, old bridge in the rain?
