Stadiums and ballparks are welcoming fans back at full capacity. Restaurants can seat guests indoors and outdoors with no minimum spacing requirement or maximum party size. And in yet another sign of the state’s progress after more than a year in a state of emergency, roadway congestion is once again crushing commuters across the region.

Traffic evaporated in the early days of the pandemic as many professional workers with the flexibility to do so shifted to remote work and schools closed their doors to the public. But now, Highway Administrator Jonathan Gulliver said Monday, transportation officials are “seeing a return to a lot of previous travel times.”

“Traffic, for all intents and purposes, is back to about 2019 levels on most roadways in Massachusetts at this point,” Gulliver said in a presentation to the Department of Transportation’s board.

That analysis came with a handful of caveats. Traffic on the Massachusetts Turnpike is still “running a little bit lower” than before COVID-19 hit, Gulliver said, particularly closer to Boston. Fewer motor vehicles are traveling through the tunnels to and from Logan International Airport than pre-pandemic.

As has been the case for much of the COVID era, commuting patterns themselves remain shifted. Gulliver said Bay Staters appear to be taking shorter trips and traveling more frequently during midday. While morning and evening rush hours are still crowded, Gulliver said they do not last as long as they did before the pandemic.

“I think we’re in for a really major adjustment period that’s going to occur throughout the fall and early winter before things settle,” Gulliver said.

The Boston area earned INRIX’s dubious designation of having the worst congestion in the country in 2019. Beacon Hill appeared poised for major debate on transportation policy shortly before COVID arrived and absorbed virtually all attention.

The news comes as MBTA officials reported part of its newest service expansion, the Green Line Extension into Medford, will be delayed thanks to the pandemic. Officials remain hopeful that service can begin on the other branch running to Union Square in Somerville by the current December 2021 goal, though that, too, already reflects a delay of about three months from a target date the MBTA quietly set earlier this year for the project’s completion.

MBTA leaders faced significant criticism for making a slew of cuts to service, including on the commuter rail, in March just as the state was beginning to reverse COVID-19 business closures. The agency pledged reverse the cuts and restore pre-COVID levels across the system “as soon as possible” and has begun bringing subway and bus service back to pre-pandemic levels.
