St. Johns Bridge - Portland, Oregon

Portland, Oregon has many bridges gracing themselves across the various waterways in and around the city. One of the most iconic of the bridges is the St. Johns Bridge, built in 1931 to cross the Willamette River northwest of downtown Portland. The suspension bridge has a total length of 3,606 feet, with a main span of 1,207 feet. The St. Johns Bridge, with its 14 soaring concrete Gothic arch piers and two steel towers that reach 40 stories into the sky, forms a dramatic entrance and exit along the Willamette River to and from Portland. The bridge was the eighth bridge to have been constructed over the Willamette River in the Portland area, and replaced the last ferry crossing of the Willamette River within the Portland city limits. Today, Bypass US 30 is routed on the St. Johns Bridge as part of the bypass route across northern parts of Portland.

The St. Johns Bridge was a bridge built by popular demand, pushed by the Peninsula Bridge Committee, led by the St. Johns and Linnton communities that had been annexed to Portland in 1915. After World War I, Portlanders built the Sellwood, Burnside and Ross Island Bridges. City residents were not very eager to vote for funding another bridge, so residents and boosters of Linnton and St. Johns went to every school and grange hall in Multnomah County, performing vaudeville acts that dramatized their need for a bridge to replace the ferry. When the St. Johns Bridge opened, it was completed 21 months after construction began and it was a million dollars under budget. When the bridge opened on June 13, 1931, the Portland Rose Festival Queen, Rachael Atkinson Hancock, cut the ribbon. The opening of the bridge began with a parade that included the Royal Rosarians and an elephant.

When it was completed in 1931, the St. Johns Bridge was expected to be a cog in the burgeoning riverfront industrial economy and something that would help Portland thrive. While many of the mills and factories along the Willamette are no longer in operation, the St. Johns Bridge is still very much part of the fabric of the community. There were a number of contracts that were submitted for the construction of the St. John's Bridge, namely known bridge designers and engineers David Steinman and Conde McCullough. The two men submitted their contracts in 1928 for the St. Johns Bridge. The selection process was controversial as some people wanted the bridge to be designed by a local like Conde McCullough, while others wanted someone with a national reputation that David Steinman had. Ultimately, the committee selected Steinman's bid. He was inspired by the hills and evergreens that surrounded Portland and wanted the bridge to match the surroundings. The suspension style that he chose for the St. Johns Bridge included soaring Gothic arches topped with copper spires, which were intended to complement the "evergreen spires" on the trees around it.

David Steinman began designing the bridge in 1928, construction began on Sept. 3, 1929 and it opened on June 13, 1931 with a total construction bond of $4.2 million. When it was completed, it was the longest suspension bridge west the Ambassador Bridge in Detroit, Michigan. Before tackling the St. Johns Bridge, Steinman was finishing the largest suspension bridge in New England at the time, the Mount Hope Bridge over the Mount Hope Bay in Rhode Island. Steinman engineered 20 bridges in 1928, and throughout his career, he engineered nearly 400 spans before his death in 1960. Steinman has been quoted as saying "If you were to ask me which bridge I love best, I would have to say the St. Johns. I put more of myself into it than any other bridge."

David Steinman preferred using the color verde green, as he wanted the bridge to blend closer with the forest on the bridge's west side. However, pilots at the nearby Swan Island airfield objected to the proposed use of verde green, pushing for a more visible black and yellow striped color scheme. It is not known why anyone would suggest this color scheme, given that lights on the towers is the traditional way of warning aircraft of tall structures. This idea was not selected for the St. Johns Bridge either, and David Steinman's suggestion of verde green to blend in with the trees was chosen to be used. The St. Johns Bridge is now painted in a different shade of green, the ODOT green that you will find as the paint color on many other bridges in Oregon.

Today, you can visit and get photos of the St. Johns Bridge from a number of viewing areas. There is a viewing platform that gives you nice views of the bridge along the Ridge Trail in Forest Park, west of the Willamette River. I find that the more accessible views of the bridge come from Cathedral Park on the east side of the river, and that is where I took the photos that you find in this article. There is a small path to the shore and a boat dock area that afford the best views of the St. Johns Bridge.

2018 Mojave Road Trip Part 2; The deadly desert highway (California State Route 127 and Nevada State Route 373)

By
After leaving Barstow via Old Highway 58 my next destination was in Death Valley.  To access Death Valley from rural San Bernardino County required a trek on north on Interstate 15 to California State Route 127 which becomes Nevada State Route 373 at the state line. Along I-15 I encountered the road sign oddity that is Zzyzx Road about eight miles south of Baker.   Zzyzx Road is a four mile road that used to go to the Zzyzx Mineral Springs and Health Spa.   The spa was founded in the 1940s and the owner made up the name "Zzyzx" to claim it was the last word in the English Language.  The spa has been shut down since the 1970s and is now part of a Desert Studies Center for California State University. The southern terminus of CA 127 in Baker is located at I-15 exit 246.  CA 127 is a 91 mile north/south highway which runs to the Nevada State Line in Inyo County.  CA 127 is called Death Valley Road from I-15 northward.  South of CA 127 ...

Finding the Pre-Emption Road of New York State

By
  The Pre-Emption Road (or rather a series of roads named Pre-Emption Road) follows a survey line called the Pre-Emption Line, drawn in the early days of the United States. The story begins with Massachusetts and New York having competing land claims to modern day Western New York State that have their roots in colonial charters granted by the British. After the Revolutionary War ended, this land became the frontier of the nation and its settlement became a priority for the new American government. During this era, there were a lot of competing land claims that needed to be settled. It was no different with the land claims between New York State and Massachusetts. On November 30, 1786, Massachusetts and New York sent representatives to Hartford, Connecticut to resolve their competing land claims. In less than three weeks, the representatives had reached a compromise. Massachusetts would receive pre-emption rights, meaning the right to sell the land after the Indian title ...

What's In a Name?: When the Roads Really Do Tell a Story

By
  Our tagline on the Gribblenation blog is "because every road tells a story". Some roads tell different stories than others. Along our travels, we may see historic markers that tell us a little story about the roads we travel or the places we pass by. Some historic markers are more general, as to telling us who lived where or what old trail traversed between two towns. During my travels across New York State and other states or provinces, I pass by many historic markers, some with interesting or amusing references to roads. I wanted to highlight a few of the markers I've seen along my travels around the Empire State and help tell their stories. Those stories may be as specific as explaining the tales of a tree that was used to help measure a distance of eight miles from Bath to Avoca in Steuben County, as referenced on the Eight Mile Tree historical marker above. They may also help point the way along historical roads first used centuries ago, or may help tell a local l...
