Openings and Construction Starts Planned for 2021

2021 is shaping up to be a major year for new transit line openings throughout the U.S.

The COVID-19 crisis put a damper on transit expansion throughout much of the world in 2020. Construction sites were paused for months, and then slowdowns followed, intended to address concerns related to worker safety. Tax revenues meant to pay for project costs declined. And ridership dropped precipitously on existing transit lines as white-collar employees were instructed to work from home. In the United States, questions were raised about what role future bus and rail service would have in an altered, post-COVID world.

Despite the death and pain the pandemic has caused, 2020 was also a year for optimism about the future of transit, especially, perhaps surprisingly, in the United States.

The pandemic made apparent to all of us the reliance our society and its economy have on underpaid, essential workers who are better users of transit than anyone else. The Black Lives Matter movement unmasked the systemic racism that underpins American society—and pointed toward the potential for new policies to promote increased social justice. The Congress made major steps toward increased funding for the nation’s transit systems, allocating $39 billion in two laws to keep trains and buses moving. And a new president, much more focused on ensuring effective public services, achieving social equity, and addressing climate change, was elected.

One can only hope, then, that 2021 will be a better year for us all. Let it be the year 1,000 transit systems bloom!

In this post, as in every year for the past 13, I catalogue all of the fixed-guideway transit projects opening and under construction in the United States. This post is built off the Transit Explorer 2 database, which is frequently updated and provides information about existing, under construction, proposed, and cancelled fixed-route transit throughout North America.

All of the projects mentioned in this post can be accessed on Transit Explorer 2.

The database has been expanded to include transit systems not only across North America, as previously, but also all of Africa and much of Western Europe. It includes more than 16,000 transit stations and about 3,000 transit lines, more than double what was available one year ago. In addition, for the first time, the database includes intercity rail lines, such as high-speed rail systems in France and Spain, and proposed projects in the United States.

Data can be viewed freely on Transit Explorer 2 or purchased for non-commercial use for $35-55 in Shapefile, GeoJSON, and CSV formats for those who would like to use the data for research or other uses, such as Excel, R, ArcGIS, or QGIS.

Previous compilations of new transit projects on The Transport Politic can be found here: 2009 | 2010 | 2011  | 2012  | 2013  | 2014  | 2015  | 2016  | 2017 | 2018 | 2019 | 2020

New transit investments completed in 2020

The COVID-19 crisis slowed work on projects throughout the world. As a result fewer investments were completed than initially planned.

Nevertheless, some major rail and bus expansions took flight. In the Bay Area, the BART rail system continued its relentless expansion around the Bay, this time making it to Berryessa on the outskirts of San Jose–the first step on an eventual route into downtown and Santa Clara. And a long-planned BRT line, the Tempo, opened, connecting parts of central Oakland.

That East Bay BRT line was one among several new-generation bus lines to open this year. Like the Uptown BRT in Houston and the Southwest Transitway in Winnepeg, the Tempo Line takes advantage of dedicated right-of-way, meaning faster service and a real improvement for passengers desperate for reliable, on-time transit.

Planned openings in 2021

If 2020’s limited number of transit openings were disappointing, 2021 is expected to pack a wallop. Eight enormous urban rail construction programs are finally coming to a head in the United States. In Honolulu, the first phase of a long-planned automated, elevated light metro line will open to serve the city’s western suburbs. In the western suburbs of Washington, D.C., the WMATA Metrorail system will finally reach Dulles Airport and, from there, head into Loudoun County. New light rail extensions in Los Angeles, San Diego, and Seattle–all under construction for decades–will finally reach completion. Streetcar projects are planned for opening in Charlotte and Tempe.

Boston’s Green Line extension into the suburban cities of Somerville and Medford, finally, will be that region’s first rapid-transit expansion for decades, adding service to downtown to some of the densest communities in the country.

Outside the United States, Edmonton and Monterrey will both be getting large expansions of their light-rail networks. Lagos will get its first heavy-rail transit line–and Alger will see an expansion of its metro into the south suburbs. In France, Rennes will get the second line in its automated metro system, and Paris will get both a new tramway line and a metro extension.

Heavy rail

  • Honolulu’s Rail Transit Phase I, connecting Kapolei to Aloha Stadium, not yet making it to the airport or downtown. The remainder of the line may take until 2033 to open, despite the project originally scheduled for completion in 2020—and at half the cost.
  • Washington’s Silver Line Phase II, providing new service west from the current terminus at Reston, and providing a new elevated station at Dulles Airport—11.4 miles for $2.8 billon. This project was delayed from a 2020 opening.

I look forward to this list every January. A wonderful collection of information, thank you.

I appreciate the work that goes into these updates. I realize the Red/Purple Modernization Project in Chicago may not represent an “opening” since its not adding any new stations or line segments. Nonetheless I would love to see it added in future updates as it represents a significant capacity expansion by virtue of (1) the new Brown Line flyover at Belmont for train capacity, and (2) reconfigured stations and widened platforms at the four stations from Lawrence northward for passenger capacity. And at $2B+, it is in fact the largest capital investment CTA has made for rail infrastructure in its history.

Please consider publicizing an initiative to build far superior rail infrastructure 10 times better, faster, and cheaper. The inability to promote and develop rail is due to the claimed astronomical cost of construction and thus, the inability of rail to pay for itself. Antiquated and piecemeal construction approaches are why Amtrak estimates costs of between $150M-$500M per mile. However, this methodology: automates the process resulting in a far superior result.
Rail hasn’t changed in 200 years. SupeRail is factory precision straight for speed while providing trolley type service, for pennies on the dollar. Because of its precision, it can use an air hockey principal that would reduce the cost and increase the speed of train cars by an order of magnitude. So much more for so much less. But even more, it can pay for itself and is so cheap that private funding will probably seek to build it.
In this funding initiative, I am attempting to simply put an affordable alternative before a legislative body so that they can no longer claim or accept claims that rail cannot be built at an affordable cost. Greatly decreased costs created the computer revolution and it is the best way to create a train revolution. In fact, this methodology is so inexpensive, we might see private concerns bidding to build rail with their money just for the state’s permission.
The entire world needs massive amounts of rail to transition away from a vehicle intensive fossil fuel world. Helping me promote an affordable construction methodology is the best way to get rail built, especially for the poorest countries in the world. If poor countries can afford to build SupeRail, their anticipated future fossil fuel needs can be avoided.

Line T Hilltop Extension is not Seattle but is Tacoma. Also you complete omit Oklahoma City’s Northwest BRT project slated for 2023 opening iirc.
