A new study sheds light on the importance of street design, especially as it relates to traffic and pedestrian safety.

In Nevada - from 2019 to 2022 - the number of traffic deaths increased 30%, according to the National Transportation Research Project.

Shima Hamidi, director of the Center for Climate-Smart Transportation and assistant professor of public health at Johns Hopkins University, helped lead the study.

She said switching lane widths between 11 to 12 feet down to 9 feet, can help reduce traffic collisions.

"But what we found in this study," said Hamidi, "a national study of more than 1,100 streets in the U.S. - is that when streets become wider, then it gives the drivers this false sense of safety that makes them drive faster."

Hamidi contended that speed is the main cause of most crashes, and when streets are more narrow, drivers tend to be more cautious.

According to the study, there are 1.5 times more crashes on roads when the lane width increases from nine to 12 feet.

The report includes policy recommendations, like prioritizing street design over driving speed and functionality.

Hamidi said another benefit to narrowing lane width relates to the environmental impact it can have on communities. She said less asphalt used for streets and roads equates to less heat.

"Really," said Hamidi, "the cause of urban heat islands - which is one of the most challenging climate change issues of our time - all of that comes with wider lanes."

Hamidi added that city and state transportation departments could pair lane-reduction projects with other initiatives, like adding bike lanes or larger sidewalks to make streets what she called "more livable."

For those worried about traffic congestion, Hamidi said narrower roads will likely slow down the speed of traffic, but that doesn't mean there will be more traffic.

"It will help many people to switch from driving to other modes of transportation," said Hamidi, "such as biking and walking, which could result in greenhouse gas emission reductions from transportation."

Massachusetts will receive close to $1 billion in federal funding to replace the Cape Cod bridges.

Lawmakers said it is the largest single bridge funding grant in U.S. history and the biggest federal grant ever awarded to the Commonwealth.

Massachusetts Gov. Maura Healy called it game-changing for the state's economy.

"It is a turning point truly in terms of sustained investments in an infrastructure whose benefits will be felt for generations," Healy emphasized. "It's a victory that we celebrate today."

The nearly 90-year-old Sagamore and Bourne bridges provide the only routes on and off the Cape and are considered "functionally obsolete" despite carrying more than 30 million vehicles each year. Healy explained plans are to focus first on replacing the Sagamore Bridge before turning to the Bourne.

The Biden Administration's Bipartisan Infrastructure Law, which established the Bridge Investment Program, invests a total of $40 billion over five years to help ensure the nation's most important bridges remain safe and operational. Already, the law has funded more than 7,000 bridge projects nationwide.

Sen. Edward Markey, D-Mass., said it feels like "Christmas in July," with the bridge project set to create some 9,000 construction jobs.

"We're going to do this with union labor," Markey pointed out. "It is going to be one of the largest union projects in Massachusetts history."

Markey noted an additional $700 million dollar state investment will allow construction on the Sagamore Bridge to begin. It is projected to be completed sometime in 2034 with the Bourne Bridge replacement completed more than a year later. The new bridges would be built next to the old ones to avoid traffic disruptions during construction.

Last week, the Senate Environment and Public Works Committee heard testimony on the state and federal response to the collapse of the Key Bridge. In addition to a recap of the cleanup efforts, testimony turned to bridge replacement and who is paying for it.

Sen. Ben Cardin, D-Md., and Sen. Chris Van Hollen, D-Md., introduced the Baltimore Bridge Response Invests and Delivers Global Economic Relief Act, in which the federal government would fund 100% of the replacement of the bridge and its approaches. Cardin said the money is needed immediately.

"We are asking for the 100%, because that's what we've done in the past and we need it now," Cardin emphasized. "Because we are lending contracts to start the construction now. We don't want to delay this. Every month it's delayed is additional loss to our communities, and frustration among drivers, not only those that are directly impacted by the port, but those that are using our streets."

The legislation requires any funds recovered from insurance proceeds or as compensation for damages be used to reduce the federal government outlay. The current estimate to replace the bridge is $1.7 billion.

The Maryland Transportation Authority is evaluating proposals from design-build teams and expects to have a team chosen by mid- to late summer. Senators in the committee focused on safety upgrades to protect bridge piers against collisions from Neo-Panamax size ships such as the container ship Dali.

Paul J. Wiedefeld, Maryland transportation secretary, said designers will ensure pier protection.

"Whether it's through islands or actually moving the piers further apart," Wiedefeld explained. "If you put these piers much further apart, obviously, that's a natural protection. That'll be played out through the design as a high priority."

The bridge rebuild completion target is fall 2028.

The Biden administration announced nearly $8 million in grants to improve public transportation, including a large and rural system in South Dakota, connecting people to critical services.

Prairie Hills Transit covers roughly the western third of the state and riders clock about 180,000 trips per year. It is receiving nearly $270,000 through a Federal Transit Administration pilot program, funded by the Bipartisan Infrastructure Law, to improve transit for people with disabilities, older adults and low-income individuals.

Lisa Johnson, deputy director of Prairie Hills Transit, said the organization will use the funds to purchase a contactless payment system for riders, an upgrade from the wood tokens the system uses now.

"By going to a contactless payment technology, we're hoping to streamline it to improve the reliability of the rider's experience," Johnson explained. "They can manage their fare card and have an ongoing history of what they're paying."

Johnson noted it will streamline operations for the transit system, negating the need to manage tokens and cash checks from riders. The system sees a wide range of ridership, she added, including low-income people, people with disabilities, seniors, veterans and youth.

The new system will include an updated website to help riders plan trips in advance. Johnson noted in an area with scattered small communities, people use public transit to go back and forth between them.

"We have five communities that are within a 20-mile radius," Johnson pointed out. "I'm hoping to link those communities in a more efficient and timely manner."

Johnson emphasized Prairie Hills Transit plans to roll out its new system in about a year.
