Spokane Street Bridge and West Seattle Bridge

Below in this photo the Spokane Street Bridge and West Seattle Bridge can be seen rising above Harbor Island and the Duwamish River.

The Spokane Street Bridge is a 1991 concrete swing bridge which replaced the earlier Old Spokane Street Bridge (AKA North Bridge) which was completed in 1924. The Spokane Street Bridge serves as the lower level of the dual structure West Seattle Bridge, the longest span is 480 feet. More information on the Old Spokane Street Bridge can be found on Bridgehunter.com

The completed Old Spokane Street Bridge can be seen on the 1924 City map of Seattle.

Interestingly the 1924 Old Spokane Street Bridge was proceeded by two other bridges. The previous bridge to the 1924 span was the Third Spokane Street Drawbridge which was a truss span completed in 1917. Previous to the 1917 the span there was an earlier truss which crossed to what was presumably Harbor Island when it was under construction in 1907 called the Second Spokane Street Bridge.

Historylink.org actually has an article on both the Third Spokane Street Bridge the Second Spokane Street Bridge.

The West Seattle Bridge was under construction from 1981 to 1984 and was meant to relieve traffic congestion on the 1924 Spokane Street Bridge. The West Seattle Bridge is Sectional Cantilever Bridge that is 2,607 feet long and has a maximum clearance of 140 feet. The West Seattle Bridge essentially part of a freeway grade west from I-5 which crosses a junction with WA 99 before leveling off to a street grade near SW Genesee Street.

When I was driving through the area I met Spokane Street at Harbor Avenue and continued east to WA 99 on the Spokane Street Bridge. The Spokane Street Bridge provided views of the substructure of the West Seattle Bridge.

The 1915-era Teilman Bridge (the only known Concrete Pony Truss Bridge in California)

The Teilman Bridge is a semi-abandoned structure over Fresno Slough west of Burrell siding near the intersection of Elkhorn Avenue and Elkhorn Grade. This structure is the only known Concrete Pony Truss Bridge constructed in California and was designed by Ingvart Teilman. Teilman's Bridge would open in late 1915 when the Elkhorn Grade was the primary road between Fresno and Coalinga. The structure would be replaced in 1991 but was left standing as it carries pipelines over Fresno Slough. Part 1; the history of the Teilman Bridge In the early Twentieth Century the most direct highway between Fresno and Coalinga followed the Elkhorn Grade. The Elkhorn Grade began at Fresno Slough a short distance west of Burrell siding. From Fresno Slough the Elkhorn Grade followed a generally southwestern course through San Joaquin Valley into the Kettleman Hills towards Coalinga. The Elkhorn Grade can be seen on the 1914 C.F.

The Dummy Lights of New York

A relic of the early days of motoring, dummy lights were traffic lights that were placed in the middle of a street intersection. In those early days, traffic shuffled through busy intersections with the help of a police officer who stood on top of a pedestal. As technology improved and electric traffic signals became commonplace, they were also originally positioned on a platform at the center of the intersection. Those traffic signals became known as " dummy lights " and were common until traffic lights were moved onto wires and poles that crossed above the intersection. In New York State, only a handful of these dummy lights exist. The dummy lights are found in the Hudson Valley towns of Beacon and Croton-on-Hudson, plus there is an ongoing tug of war in Canajoharie in the Mohawk Valley, where their dummy light has been knocked down and replaced a few times. The dummy light in Canajoharie is currently...

Prunedale Road (Monterey County)

Prunedale Road is a short 2.6-mile-long frontage corridor of US Route 101 in the namesake Monterey County community of Prunedale. Prior to 1932 US Route 101 bypassed Prunedale in favor of the San Juan Grade to the east. Prunedale Road along with nearby Moro Road served as an alternative connecting highway between Salinas and San Juan Bautista. Following the realignment of US Route 101 onto the Prunedale Cutoff the former through route along Prunedale Road would be rendered as a western frontage. Part 1; the history of Prunedale Road Prunedale Road is located in and is named after the Monterey County community of Prunedale. Said community was founded near the junction of San Migeul Canyon, Langley Canyon and Echo Valley. Watsonville settler Charles Langley (namesake of Langley Canyon) was one of the prominent early community settlers. The Prunedale Post Office would open for the first time in 1894 but would close by 1908. Early agricu...
