The crash that killed Boston city worker and bike enthusiast Louisa Gag last week involved an 18-wheeler recycling truck that had maneuvered around a turning vehicle on busy Tremont Street and then continued on for at least a few blocks after the collision, according to two people familiar with the investigation.
The driver appears to have been heading east on Tremont Street shortly after 8 a.m.
July 9, when it approached a vehicle that was turning left.
At that point, the driver steered right to go around the car and collided with Gag, the two sources told the Globe.
Those details emerged as Mayor Michelle Wu on Thursday evening vowed to “accelerate” street safety projects after more than a year of criticism from advocates that she’d slow-walked bike infrastructure and other road improvements.
She also promised a “full analysis” of the street design in the area of the fatal crash and beyond.
“I can’t stop thinking about Louisa.
We owe Louisa more than our grief.
We owe her action.
We have to do better,” a tearful Wu told a crowd of cycling advocates who had gathered for a vigil outside City Hall Thursday evening.
“And while I know the purpose of tonight is to focus on celebrating her life, I want you also to know that the city is taking action.”
Police have said little about the incident beyond that it remains under investigation.
But the details newly disclosed on Thursday bring further clarity to a crash that has led to an intense debate over whether better safety protocols could have prevented it.
The two people who shared details about the fatal crash spoke on the condition of anonymity because they are not authorized to speak about the case.
The driver of the truck has not been identified and has not been charged with any crime.
The new details do not indicate whether there was any wrongdoing.
The driver stopped the truck near Tremont’s intersection with Melnea Cass Boulevard.
Police spoke with the driver at that time.
The truck is owned by Allied Recycling and that morning had departed a demolition site at One Joslin Place, where a major hospital project in Boston’s Longwood area is underway.
In a statement, Allied Recycling confirmed its truck was involved and said the company is working with police “to determine what happened.”
The company said it has turned over all information requested by authorities.
“We were deeply upset to learn of her death and mourn with the rest of the community,” a spokesperson said in a statement.
In response to a request to identify the driver, the spokesperson said: “While we are still trying to better understand the accident, the driver involved is one of our best — an experienced and responsible driver.
Safety is of the utmost importance to our company and we continue to work closely with authorities."
Crash investigations often take months to resolve.
A lawyer for Gag’s family declined to comment on their behalf.
The death of Gag has triggered an outpouring of grief and anger from Boston’s cycling community.
A popular evangelist for cycling, she worked as a bike-share and transportation planner for the city.
Gag, 36, grew up in Roslindale, graduated from Boston Latin School, and earned degrees at the University of Rochester and Tufts University.
She “worked tirelessly to improve the city she loved, devoting herself to making it more livable, enjoyable, and humane,” according to her obituary.
Advocates and her City Hall co-workers — including Wu, for whom she was an intern years ago when Wu was a city councilor — remembered Gag as a kind, consistent, and committed friend.
At the vigil Thursday, friends and colleagues shared memories of Gag and her dedication to making Boston streets safer for cyclists and pedestrians.
After a moment of silence, the talk at the vigil turned to action.
“I’m sad and I’m frustrated, but we aren’t helpless,” said Brendan Kearney, executive director of WalkMassachusetts and a part of the Massachusetts Vision Zero Coalition.
“Look around here, we’re all connected to one person, from one crash.
We’re going to make a difference and we’re going to keep showing up.”
Her death also put a harsh spotlight on Wu’s handling of street safety improvements, and led to criticism the city delayed many street infrastructure projects over the past year and a half, including some near the site of the crash.
Wu’s office said in a statement Thursday that, “We owe it to Louisa, her loved ones, and everyone who uses our streets to ensure a thorough, transparent investigation that establishes the facts and provides a clear understanding of exactly what happened.
The City will continue working closely with the Boston Police Department and the District Attorney to support the investigation.”
The crash occurred near the office of Boston’s Cyclist Union, and members have said they’ve repeatedly raised safety concerns about cycling on Tremont Street.
That section of Tremont in Mission Hill is a tight, two-lane road running between two busy interchanges, Brigham Circle at one end and and Roxbury Crossing at the other.
It has a painted bike lane delineated at times by solid lines and others by dashes.
There are bus stops nearby and spots for cars to park.
The intersection of Tremont and Parker streets, where the crash occurred, was part of an area the city identified in 2023 as needing improvements.
But the project does not appear to have advanced since then, and is on a list of those that advocates say were paused, or not updated by the city for more than a year.
Wu has said street safety remains a priority for her administration, and emphasized that work on many such infrastructure projects is ongoing.
Wu’s office said last week the location of the crash was not covered under the Parker Street-area planning process and that there never were plans for a protected bike lane there.
At the vigil for Gag Thursday, Wu said she would assign two senior officials to the Streets Cabinet “to accelerate the policies, planning, and capital delivery work that will make our streets safer.”
The crowd of at least 200 had gathered at City Hall after riding bikes from the site of Gag’s death.
They also delivered a blistering open letter to Wu demanding she take a series of actions to address street safety issues.
Titled “Enough is Enough,” the letter emphasizes that the majority of the signatures, tallying 4,000, are from Boston parents and residents who have pleaded with Wu for safety improvements for years.
