The Lasting Legacy of the 1913 Bion Arnold Report

The Lasting Legacy of the 1913 Bion Arnold Report
By Jeremy Menzies

Looking back at San Francisco’s transportation history, one study from 1913 has impacted the city’s transit system for over 100 years. Commissioned by city officials, the “Report on the Improvement and Development of the Transportation Facilities of San Francisco” by engineer Bion J. Arnold, is a comprehensive study of transit in the city. The 450-page report covers everything from rush hour congestion to plans for a Market Street subway. This document is essential to understanding our city’s transportation history and some of its recommendations are still in use today.

This 1910 view of Market and Sutter streets shows just some of the complex issues that the Arnold report addressed.

 

Building Muni

One section of the report is entirely dedicated to specifications for building and improving the city’s cable and street cars. Muni’s very first streetcars, frequently called “Arnold” cars, were specified based on construction cost, passenger comfort, ease of operation, and even the unique climate of San Francisco. Today, historic Streetcar 1 is one of these streetcars that still runs in special service.

This photo of one of Muni’s first streetcars was used on page 178 of the report and shows the open end sections, boarding platforms, and “automatic” ventilation features specified by Arnold.

In addition to the vehicles, Muni’s earliest lines, and service to the 1915 Panama Pacific Exposition, were all directly influenced by the report. Versions of the A, B, C, E, F and H streetcar lines all appear in the report. It also influenced later lines like the J, K, L, and M.

Tunnels & Streets

The report also detailed several tunnels and street changes throughout the city meant to speed travel across town. Of the more than ten tunneling projects proposed, the Stockton Street, Twin Peaks, and Sunset tunnels were all built by 1930. The Broadway tunnel followed in the early 1950s.

Among the street changes proposed, the extension of Market Street over Twin Peaks was perhaps the largest. This extension was built alongside the Twin Peaks Tunnel in 1917-18.

Improving and Expanding Transit

Arnold also called for a consolidated transit system and a subway under Market Street, both of which were achieved by the mid-20th Century.  In 1944, voters approved the purchase of the Market Street Railway Company, the largest transit operator in SF. This merger unified public transit service under Muni. Instead of navigating two competing services, riders finally had a one-fare ride to virtually anywhere in town. Consolidation also allowed improvements to be made across the system.

Signs in drawing read "Fifth Street" as station name, directional signs reading "To 5th Street", "Exit to 5th", "To Powell Street". Streetcar headsign reads "Ocean Avenue".

Bion Arnold’s Market Street subway plans were just one of many ideas floated over the years. This drawing from 1937 shows a proposed subway station at Powell and Market streets.

 

Arnold’s report is one of the earliest documents to include clear plans for a Market Street subway. 50 years later when Bay Area voters approved general obligation bonds to build BART & Muni Metro, elements of Arnold’s subway showed up in the design.

Ongoing Legacy

Even today, suggestions from the report can be found in the SFMTA’s Muni Forward and Vision Zero Quick Build programs. Moving and consolidating stops, increasing boarding area size, building transit boarding islands, and all-door boarding are all mentioned in the 1913 document.

A common sight today, double-length platforms and two-car trains like those pictured here were just two improvements to transit service recommended by the Arnold report.

The Arnold report is one of the most extensive studies of transportation in San Francisco. 109 years later, many of the changes recommended by the report have become normal parts of our streets and transit system.

New top story from Time: Angry Youths Rattle Spain in Support of Jailed Catalan Rapper Pablo Hasel

https://ift.tt/2NUGSpC BARCELONA, Spain — The imprisonment of a rap artist for his music and tweets praising terrorist violence and insulting the Spanish monarchy has set off a powder keg of pent-up rage this week in the southern European country. The arrest of Pablo Hasél has brought thousands to the streets for different reasons. Under the banner of freedom of expression, many Spaniards strongly object to putting an artist behind bars for his lyrics and social media remarks. They are clamoring for Spain’s left-wing government to fulfill its promise and roll back the Public Security Law passed by the previous conservative administration that was used to prosecute Hasél and other artists. Hasél’s imprisonment to serve a nine-month sentence on Tuesday has also tapped into a well of frustration among Spain’s youths, who have the highest unemployment rate in the European Union. Four in every 10 eligible workers under 25 years old are without a job. “I think that what we ...

New top story from Time: How Facebook’s Australia News Ban Could Hamper Vaccine Rollout to Aboriginal People

https://ift.tt/37E8rL1 The COVID-19 vaccine rollout was never going to be easy in Australia’s sparsely populated, desert-covered Northern Territory. With many small towns located hours apart by road, organizers even considered using drones and dry ice to make deliveries. But the vaccination campaign is facing an even greater uphill battle after Facebook removed news content across the country of 25 million on Feb. 18 following a battle over a bill that would force Big Tech companies to pay for the use of news stories. The ban also swept up Indigenous media organizations, meaning that Aboriginal people, who make up more than 25% of the region’s population may not have access to reliable information about vaccinations. Many Aboriginal people rely on Facebook as a portal to the Internet. During the COVID-19 pandemic, Facebook has become “a primary vehicle for promoting health information to remote Aboriginal communities,” says Malarndirri McCarthy , a senator in the Northe...

New top story from Time: How a Belarusian Teacher and Stay-at-Home Mom Came to Lead a National Revolt

https://ift.tt/3bD4WG2 On a hot summer day last August, Svetlana Tikhanovskaya was pacing up and down her empty apartment in Minsk, the capital of Belarus in Central Europe, her life—and her country—in turmoil. With her husband in jail, she had sent her two small children out of the country, to safety, and she now faced a stark choice, bluntly handed to her by the nation’s hard-line security forces: flee into exile herself, or face arrest. “I had a couple of hours, but I could not pack anything, because I was so overstressed,” she recalls. “It was a shock. I was not prepared for this.” Indeed, it is hard to imagine how Tikhanovskaya could have prepared for the jolting transformation of her life. Within the space of a few months, she emerged from obscurity to become the leader of Belarus’ biggest revolt in decades, determined to bring down President Alexander Lukashenko, who has ruled the former Soviet republic with an iron hand for more than 26 years as what many call Euro...

New top story from Time: President Rodrigo Duterte of the Philippines Has Changed His Mind About Scrapping a U.S. Security Pact

https://ift.tt/3fe21WW MANILA, Philippines — Philippine President Rodrigo Duterte has retracted a decision to end a key defense pact with the United States, allowing large-scale combat exercises between U.S. and Philippine forces that at times have alarmed China to proceed. Duterte’s decision was announced Friday by Defense Secretary Delfin Lorenzana in a joint news conference with visiting U.S. counterpart Lloyd Austin in Manila. It was a step back from the Philippine leader’s stunning vow early in his term to distance himself from Washington as he tried to rebuild frayed ties with China over territorial rifts in the South China Sea. [time-brightcove not-tgx=”true”] “The president decided to recall or retract the termination letter for the VFA,” Lorenzana told reporters after an hour-long meeting with Austin, referring to the Visiting Forces Agreement. “There is no termination letter pending and we are back on track.” Austin thanked Duterte for the decision, which he sai...

New top story from Time: ‘I Will Cry When I Deliver That Last Yogurt.’ Small Ranch Owners Are Selling Their Herds For Lack of Water

https://ift.tt/3l9IavO Gail Ansley delivered her final batch of homemade Picabo Desert Farms goat yogurt to Atkinson’s Market in Hailey, ID two weeks ago. As usual, each 16-oz unit of rich, creamy goat’s milk yogurt was packaged in a plain plastic container with a simple disclaimer stuck to the lid: “We know this label isn’t Chic, but the Yogurt inside is the best you’ll Eat!” it proudly proclaims . The ingredients: raw goat milk, culture, and sometimes gourmet vanilla bean paste sourced from nearby Boise, or fresh lemon curd, or peach jam. But this chapter is all over: she sold her last goat, a Nigerian dwarf named Kea, the weekend before. Kea was the final remaining animal in Ansley’s hundred-plus goat herd, which she grew and raised over the past six years on her small farm in Richfield, ID. “ And I will cry when I deliver that last yogurt tomorrow, ” Ansley says over the phone, audibly tearing up. “ When we started, my husband had a pickup truck and a camper, that’s wha...

New top story from Time: Protests Against an Abortion Ban Continue for a Fifth Day in Poland

https://ift.tt/2HDCNDx WARSAW, Poland — Women’s rights activists and many thousands of supporters held a fifth day of protests across Poland on Monday, defying pandemic restrictions to express their fury at a top court decision that tightens the predominantly Catholic nation’s already strict abortion law. In Warsaw, mostly young demonstrators — women and men — with drums, horns and firecrackers blocked rush-hour traffic for hours at a number of major roundabouts. Some of them took off their shirts and stood topless on top of cars. Many held banners with an obscenity calling on the right-wing government to step down. A group of far-right supporters held a counter-protest in front of a church and police in riot gear kept the two groups apart, using pepper spray at one point. Some of the people protesting the court ruling were detained and others sat down in the street to stop the police van taking away the detainees. A protesting woman was taken to hospital with slight in...

New top story from Time: DOJ Reportedly Investigating Whether New York Gov. Cuomo Manipulated Data on COVID-19 Nursing Home Deaths

https://ift.tt/3u8AJab (ALBANY, N.Y.) — New York Gov. Andrew Cuomo faced mounting challenges to his leadership on the coronavirus pandemic Wednesday as state lawmakers threatened to strip him of the power to issue emergency orders and federal investigators scrutinized his administration’s handling of nursing home data. The U.S. Justice Department has been examining the governor’s coronavirus task force and trying to determine whether the state intentionally manipulated data regarding deaths in nursing homes, two people familiar with the matter told The Associated Press. The people, who weren’t authorized to discuss the investigation and spoke on condition of anonymity, said the Cuomo administration had not been cooperative with prosecutors, especially in the early stages of the probe, and for months had not produced documents and other data the Justice Department had requested. The inquiry began months ago in the Justice Department’s civil division, and parts of it have ...

Van Ness Improvement Project Nears Completion

Van Ness Improvement Project Nears Completion By Nehama Rogozen After years of planning and construction, work on the Van Ness Improvement Project is progressing rapidly and the end is in sight! Construction is projected to be finished by the end of this year, with Bus Rapid Transit (BRT) service running on Van Ness Avenue from Mission to Lombard beginning in early 2022. Work on the red transit lanes between Broadway and Pacific is almost complete. Crews have been busy on Van Ness Avenue. You may have noticed them building new medians and sidewalks, paving the roadway and installing poles that provide lighting and power to the BRT system. Most recently they have installed the red lanes that will allow buses to move Muni and Golden Gate Transit riders quickly along the corridor, without getting stuck in traffic. To ensure durability and reduce fading, these red transit lanes are made from poured red concrete, as opposed to red paint or thermoplastic on top of concrete. We are als...
