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.

Washington state is receiving nearly $90 million in federal infrastructure funding, from the Biden Administration. The funds were distributed by the Rebuilding American Infrastructure with Sustainability and Equity, or RAISE program and will boost eight projects in Washington.

One recipient is the Kitsap County Public Transportation Authority, which is using the grant money to upgrade its transportation hub and clean up its bus fleet.

John Clauso, executive director of Kitsap Transit, said they're constructing a full-service maintenance facility, and not only to work on their diesel buses.

"Also, we're in the transition phase of converting all of our buses to battery electric buses, as well as we're exploring and wanting to move into the hydrogen fuel cell technology," he said.

The project is receiving $17 million from the RAISE program. It will help Kitsap Transit in its goals of a fully electrified fleet by 2050. Kitsap Transit serves Kitsap, Clallam, King, Jefferson and Snohomish counties.

Clauson said the grant is also helping with the purchase of electric double decker buses, which are needed for the increasing demand Kitsap Transit is seeing. He said the funds from the RAISE program are critically important to moving this project forward.

"The facility that we've put in for fueling and the bus-washing - that is all designed for a double deck coach that we have no where to maintain one. So, we've held off on the acquisition of double deck buses simply because we don't have a facility that we could maintain those buses in," he said.

The RAISE program is distributing funds from the infrastructure law passed in 2021. The eight Washington state projects were part of a larger announcement from the U.S. Transportation Department about its distribution of $1.8 billion in funds to nearly 150 projects across the country.

Electric-vehicle owners in North Dakota have long called for more action to boost the state's charging station network. There continues to be mixed messages policy-wise, but officials are moving forward on funding opportunities.

As part of federal funding awarded to all states, North Dakota is now taking applications for private entities to tap into these dollars and place fast-charging stations along Interstates 94 and 29.

Russ Buchholz, innovation manager with the North Dakota Department of Transportation, said a lack of these options has kept North Dakota's EV adoption rate low. But he hopes this latest step will inspire more confidence among current owners, as well as other consumers.

"If they know they can travel through our state pretty much at ease, and these are Level 3 chargers -- so it would take roughly about 15 minutes, maybe a half-hour to charge their vehicle -- I think there'll be a little acceptance," he explained.

Buchholz added this might convince more out-state-travelers to pass through North Dakota. The federal program pays up to 80% of project costs, but state lawmakers heavily restricted government agencies, including municipalities, from participating.

Separately, Gov. Doug Burgum has publicly criticized the movement, but ultimately agreed for the state to join regional planning for EV infrastructure.

In an oil-producing state with a largely rural backdrop, Buchholz admits opinions on EVs can be strong. He said if not enough applicants come forward to construct and own privately operated charging stations, they'll have to go back to the Legislature in hopes government agencies will get their chance.

"And that would allow, I'll say, a little more freedom and maybe a better partnership, " Buchholz continued.

No matter the political appetite, Buchholz predicts more of the transportation sector will be running on electric sources in the future. That's even with North Dakota now having fewer than one thousand registered EVs. He pointed to other developments -- such as construction equipment maker Bobcat producing electric machinery in Bismarck -- as examples that might help win over skeptics.

Representatives from Union Pacific Railroad will attend a town hall meeting in Council Bluffs tomorrow night to hear about the so-called "triangle of death" being created by the alignment and traffic on some of its tracks.

The chronically blocked tracks are frustrating to residents but also potentially deadly, some residents said. Council Bluffs used to be home to eight rail companies. They've consolidated to four, but there are still 48 crossings in town and people in about 50 homes are trapped by tracks on two sides.

Andrew Whitehill, a resident of Council Bluffs, said he sees drivers every day create dangerous situations in a residential area where children are playing.

"'I can't afford to get stuck at this train,'" Whitehill said drivers are thinking. "They'll see the train coming and will then drive a few blocks down and try to speed past it to beat it, because they're not trying to get trapped in the triangle."

It is more of an issue now because as rail carriers have consolidated, the trains making cross-country trips are longer, stretching well beyond the rail yard and onto tracks in the city, blocking crossings. The town hall is scheduled for 6:30 p.m. Tuesday in the police department building. Union Pacific has said it is committed to a fix.

Matt Walsh, mayor of Council Bluffs, said Union Pacific representatives expressed surprise over the blocked tracks when he met with them but added the company is willing to make changes, including by installing new technology.

"They can send a signal to a beacon, to alert people that the tracks are blocked," Walsh explained.

While the fix could help keep people from getting into the triangle in the first place, it does not do anything to help those who are already there. Union Pacific has told the mayor the company will schedule trains differently to avoid having both sets of tracks occupied at once and a new yard master will make sure it happens.
