Wisconsin's largest city has seen recent debate over highway expansion plans amid environmental concerns, and a new study suggested for similar projects, some effects could be limited if narrower traffic lanes are prioritized.
The expansion plan in Milwaukee involves a stretch of Interstate 94. Research from the Johns Hopkins Bloomberg School of Public Health was more focused on urban roadways with speed limits of around 35 miles an hour.
Shima Hamidi, director of the Center for Climate-Smart Transportation and assistant professor of public health at Johns Hopkins University who helped lead the study, said switching from lane widths between 11 and 12 feet, long the norm, down to 9 feet helps reduce traffic collisions. She pointed out it also leaves more room for options not involving vehicles.
"It will help many people to switch from driving to other modes of transportation, such as biking and walking," Hamidi explained. "Which could result in greenhouse gas emission reductions from transportation."
The study contended with narrower lanes, people will not feel compelled to drive as fast and will be more alert. Hamidi acknowledged while the approach might slow traffic, past research shows minimal effects, which means the changes would not cancel out environmental benefits. Other studies have shown expanding the number of lanes, in general, does not reduce congestion.
Hamidi also noted transportation planners and engineers have expressed liability concerns, but she emphasized her team's study is one of the first to give cities and states firm data, on the traffic safety side, showing skinnier lanes are more effective.
"We are getting more and more interest from transportation planners, mostly at the local level," Hamidi observed. "Cities are eager and interested to really see how this could be implemented."
Hamidi added the next steps involve more research to quantify some of the other impacts, including air pollution. The study issued this month analyzed nearly 1,200 streets in seven cities around the
U.S. The findings come amid a gradual increase in pedestrian fatalities over the past decade.

The number of registered electric vehicles in Indiana rose from 13,000 in 2023 to nearly 15,000 in 2024. However, plans to install more EV chargers in Indianapolis are on hold due to President Donald Trump's executive order to freeze federal spending linked to the 2024 Biden-Harris Administration Bipartisan Infrastructure Law.
Mo McReynolds, interim director of the Office of Sustainability for the City of Indianapolis, said the city applied for funding between 2021 and 2024 and was approved for millions last year and should the federal government authorize funding distribution within weeks or months, plans will designate local charging and fueling infrastructure sites to appear at popular neighborhood places.
"We were awarded $15 million, in that realm, to establish as many sites as we can afford within that budget," McReynolds explained. "We're still determining that amount within a partnership with Indianapolis public libraries, Indy park locations and culturally relevant sites for Black and brown communities."
Investments will make modern and sustainable infrastructure accessible to all drivers of electric, hydrogen, propane and natural gas vehicles. Indiana Vehicle Fuel Dashboard data shows Marion County has the highest number of state-registered vehicles under the four categories at slightly under 3,000. Union County has the lowest with four vehicles.
Pending funding disbursement, McReynolds pointed out the initial $15 million grant timeline is for five years. It is meant to coordinate with the National Electric Vehicle Infrastructure program for corridors and highways. Her office is establishing a grant agreement with the Federal Highway Authority for projects on a more local level.
"Ours are more focused on the community, so we hope to begin that process this year," McReynolds emphasized. "We may begin procurement with EV charging companies in 2026."
A significant amount of time will be taken to evaluate current and potential sites in Indianapolis. McReynolds indicated her office intends to do proper community engagement by speaking with residents to ensure EV chargers are welcome in their communities. Due to Trump's executive order to hold off on fund disbursement, Indianapolis Mayor Joe Hogsett is monitoring any further developments and is awaiting further guidance.

Massachusetts will benefit from more than $100 million in new federal funding for various transportation projects.
Neighborhoods divided by busy roadways in Somerville, Mattapan and Pittsfield will be reconnected with new street-level pathways while more than 400 new electric-vehicle charging ports will be installed statewide.
Quentin Palfrey, director of federal funds and infrastructure for the Massachusetts Executive Office for Administration and Finance, said funds will also improve more than 50 high-risk rail crossings.
"Some of these new resources are going to help us to expand rail and transit, move forward West-East rail and also improve the safety of our transit system," Palfrey outlined.
Palfrey noted the goal is to create a more accessible and climate-resilient transit system. The state has secured more than $9 billion in federal funds over the past two years, including nearly $2 billion to replace the Cape Cod Bridges.
The funding stems from the Bipartisan Infrastructure Law, the largest federal investment in public transportation in the nation's history. In addition to upgrading existing structures, projects are also improving access to natural resources.
Palfrey pointed out more than $17 million will support expansion of the Ashuwillticook Trail, creating a network of paths from Adams to Williamstown.
"It's a major priority across our transportation system," Palfrey emphasized. "This is going to be a really big step forward for Berkshire County's efforts in that regard."
Palfrey added state officials are building a transit network to serve everyone no matter how they travel, while helping to meet the state's ambitious climate goal of net-zero emissions by 2050.

A leading consumer publication says electric vehicles are gaining ground on gas-powered cars when it comes to feelings about reliability.
However, an EV enthusiast and Nebraska electrical engineering professor and said there's an information gap, while also highlighting improved technology.
The new reliability survey from Consumer Reports found that EV owners reported 42% more problems than gas-only cars.
That compares to nearly 80% from the previous survey, indicating a major improvement.
Retired University of Nebraska professor Don Cox said the batteries in most EVs are much better than they used to be, potentially easing concerns about them performing in colder climates.
"Batteries have improved a lot over the last 10, 15 years," said Cox. "A huge amount. They are continuing to improve."
However, he said EV batteries will always need a little time to warm up when it's cold, impacting their range in the winter.
Even though that perfection might never be achieved, Cox and other researchers say EVs are proving to be more efficient than gas models, overall.
He said he disagrees with how Consumer Reports puts together its evaluations, and added there isn't enough widely circulated ratings for buyers to lean on.
Dissecting issues such as reliability often coincides with measuring sales of electric vehicles. Cox was one of the first EV owners in Nebraska, which still lags other states for these purchases.
But with the help of federal investments, he said more chargers are being added, including near interstates to accommodate longer trips.
And the median range has increased from 80 miles in 2010 to roughly 250 miles today.
"I think that as people understand more about electric cars," said Cox, "that they're going to be more useful almost everywhere."
Nationally, researchers say issues still have to be sorted out in building up a strong charging network.
That includes drivers encountering broken charging equipment and the need for these sites to be maintained.
