Most bridges from the 1980's and later use a variation on the "Jersey barrier" and do not differ much in the railing style from state to state.
The styles shown here are mostly from the 1950's-70's when the rail styles were more distinct.
A newer version of the bar design, used in Arizona up to the late 70s. These photos are from Interstate 10 west of Phoenix.
Top: Westbound over the Hassayampa River.
Bottom: Near Avondale, taken on opening day for this stretch of I-10, October 17, 1978.
The bar design shown on this page for Oregon, along with the bar design of the first one shown for
Hawaii (below), is also seen in Arizona.
Hawaii
The style of rail on the left is used in many states. On the right is a style similar to the California flat rail design.
This the most common style I noticed in Hawaii, a bar mounted on top of a "Jersey barrier".
Also see my Hawaii Roads page.
New Mexico / Texas
I-40 bridges, New Mexico on the left and Texas on the right.
Thanks to Mike Ballard for these two photos.
Oregon / Washington
Old Oregon U.S. 101 sign.
This is the bar style as seen in Portland, Oregon (top) and Tacoma, Washington (bottom). Note that in the Washington design the bar is oriented away from the road and the Oregon design orients the bar toward the road.
