It’s National Roundabouts Week. Who knew? Sep 24, 2026

Show notes

The Federal Highway Administration (FHWA) has declared this week, Sept. 21-25, as National Roundabouts Week. The Michigan Department of Transportation (MDOT) has installed roundabouts at various intersections, when appropriate, for several years.

On this week’s edition of the Talking Michigan Transportation podcast, a conversation with MDOT Engineer of Traffic Safety Garrett Dawe about the life-saving benefits of roundabouts.

According to the FHWA, roundabouts reduce intersection crashes resulting in death or injury by an average of 82 percent. They also reduce traffic delays by 62 to 74 percent while often costing less than traditional signalized intersections over their lifespan due to lower maintenance and operational requirements.

Several cities across Michigan and in several other states have been aggressive about installing roundabouts. One in Indiana, in particular, is considered the roundabout capital of the United States.

What’s next for the iconic Tunnel of Trees? Sep 17, 2026

Show notes

Just as crews began repairing sections of M-119 (also known as The Tunnel of Trees) damaged by April flooding, heavy rains in June wreaked havoc on more sections of the popular tourist route in Michigan's northern Lower Peninsula.

Following completion of a $300,000 project to stabilize the slope beneath a section of M-119 near West Stutsmanville Road damaged in the spring flooding, the Michigan Department of Transportation (MDOT) announced in early September that it has reopened M-119 between West Stutsmanville Road and Terpening Road.

This map shows current status and detour routes.

On this week’s edition of the Talking Michigan Transportation, an update from MDOT North Region Engineer Bill Wahl on work that’s been completed on M-119 and what long-term challenges remain for the corridor. He also talks about some of the other roads in MDOT's North Region damaged in the spring flooding.

Finally, Wahl offers details on construction of a diverging diamond interchange (DDI) at the I-75/M-32 intersection in Gaylord. The first such interchange to be built in northern lower Michigan, a DDI is an alternative interchange that improves safety, increases traffic flow and can reduce construction costs.

Reprise: DNR boosts hunting to help farmers, reduce car-deer crashes Sep 10, 2026

Show notes

As fall approaches, and on the heels of last week’s discussion about creating safe crossings to prevent deadly and costly vehicle-wildlife crashes, we are reprising an episode from 2024 featuring a discussion with Michigan Department of Natural Resources (MDNR) Public Information Officer Ed Golder.

Golder talked about the decline in deer harvests being reported by hunters and an innovative program, now called Hunters Feeding Michigan, a name change from what was mentioned in the original podcast.

Since then, Golder says the MDNR is doing more than ever to help farmers get deer off their land. I hope you enjoy this encore presentation.

The podcast covers themes featured in a Detroit Free Press story detailing other creative efforts by the MDNR to stem the proliferation of deer in the state’s southern regions.

Golder explained the challenges and how wildlife officials are tackling them.

Study moving forward to prevent vehicle-wildlife crashes Sep 02, 2026

Show notes

Research indicates as many as 2 million vehicles collide with large wildlife in the United States each year, resulting in as many as 200 human deaths, more than 26,000 injuries and billions of dollars in property damage.

Officials in Michigan hope to join other states in finding creative ways to address the problem.

On this week’s Talking Michigan Transportation podcast, Amanda Novak, a resource specialist at the Michigan Department of Transportation, talks about her work in conjunction with the Michigan Department of Natural Resources to study these collisions and ways to create safer crossings.

Environment America reports that a survey of Americans about their views on wildlife crossings found that nearly 90 percent of them support the concept.

Progress on a Michigan road user charge project Aug 27, 2026

Show notes

On this week’s Talking Michigan Transportation podcast, a conversation with Jennifer Roberts, national road usage charge (RUC) discipline lead at CDM Smith, the consultant selected by the Michigan Department of Transportation to study and eventually pilot transitioning Michigan’s primary road funding formula to an RUC instead of the gas tax.

The Michigan Legislature in 2025 directed MDOT to begin the study and pilot program.

Roberts provided a project overview and the tasks ahead, including project management, planning and procurement, statewide public outreach and education, legislative engagement, operational pilot, revenue modeling and, finally, findings and completion of a report.

She also talks about what she’s learned from other states in various phases of studying or piloting alternative methods of paying for transportation, as discussed on the podcast previously with the Washington, D.C.-based Mileage Based User Fee Alliance (MBUFA).

Feds ease rules to expedite deployment of robotaxis Aug 20, 2026

Show notes

This week’s edition of the Talking Michigan Transportation podcast features another conversation with Joann Muller, who writes the Axios Future of Mobility newsletter.

Muller talks about her recent reporting on Amazon’s Zoox (pronounced "zooks") robotaxis. The National Highway Traffic and Safety Administration (NHTSA) granted a temporary exemption to commercially deploy up to 2,500 robotaxis annually for two years.

All of this comes as Waymo, Uber and other companies make investments in the rapidly evolving automated vehicle (AV) industry and encounter hiccups along the way.

Muller also talks about a recent road trip she made through Wisconsin in a Rivian R2. She was pleased to find a robust charging network eliminating any range anxiety. She was also impressed with Rivian’s use of adaptive driving beam (ADB) headlights and talked about why the technology has been developed more slowly in the U.S.

From the newsletter:

A decade after shape-shifting headlights changed nighttime driving in Europe, the technology remains remarkably scarce in North America - a case study in how U.S. regulations can slow the arrival of proven safety innovations.

The Gordie Howe International bridge: Memories from the trenches Aug 12, 2026

Show notes

On July 27, with little fanfare, the long-awaited Gordie Howe International Bridge (GHIB) opened, creating a vital commercial link between Detroit and Windsor, Ontario.

On this week’s Talking Michigan Transportation podcast, conversations with two people who played important roles in the earliest days of conceiving and planning what became the GHIB.

First, Kirk Steudle, director of the Michigan Department of Transportation (MDOT) from 2006 to 2018, talks about the early planning and discussions about a location, environmental clearance and why it took so long as the name changed from the Detroit International Trade Crossing (DRIC) to the New International Trade Crossing (NITC) to finally becoming the GHIB.

Steudle recalls the support and advocacy from previous Michigan governors, Jennifer Granholm and Rick Snyder, and Gov. Gretchen Whitmer’s work to get the project over the finish line.

The discussion includes some observations from a Detroit News story outlining the timeline and battles.

Later, Mohammed Alghurabi, a senior project manager at MDOT who led community outreach efforts and built vital relationships in the southwest Detroit neighborhood where the bridge is anchored on the U.S. side, recalls the trials and tribulations and his thrill at seeing the bridge open to traffic.

A long-awaited celebration at the Blue Water Bridge Aug 06, 2026

Show notes

On this week’s Talking Michigan Transportation podcast, Amy Winn, the Michigan Department of Transportation (MDOT) administrator at the Blue Water Bridge in Port Huron, talks about completion of the first of four components to fulfill long-time hopes to improve the flow of traffic at the bridge.

Officials from MDOT, the City of Port Huron and others are celebrating the completion of Component 1 and highlight a sound wall and pedestrian path completed as part of the larger plaza expansion project.

This component came with a $36.3 million investment, including a $25 million federal INFRA grant.

Also discussed was the bridge’s rich history.

Progress update on MDOT’s electric vehicle charging program Jul 22, 2026

Show notes

It has been five years since adoption of the Bipartisan Infrastructure Law, which, among many things, included federal funding for the National Electric Vehicle Infrastructure (NEVI) program. Michigan was fortunate to receive $110 million of those funds. On this week’s Talking Michigan Transportation podcast, Steve Minton, who heads the Michigan Department of Transportation’s (MDOT) Office of Major Projects, provides an update on progress in executing contracts and installing chargers across the state’s NEVI program.

Minton helped launch the MDOT program and offers his insights on the challenges and rewards of contracting, installation and meeting the needs of electric vehicle users.

Reimagining the U.S. Interstate system at 70 Jul 15, 2026

Show notes

A national effort, entitled the “Reimagining America’s Interstates” initiative, is collecting comments on new interstate facility suggestions, feedback on major upgrades needed on existing routes, and how the system can better meet the needs of the 21st century traveling public.

The Federal Highway Administration (FHWA) announced this new initiative during a June 30 media event that also celebrated the 70th anniversary of the “Dwight D. Eisenhower National System of Interstate and Defense Highways,” created when President Dwight Eisenhower signed into law the Federal Aid Highway Act of 1956, along with the unveiling of “Freedom 250” highway signs in celebration of that anniversary.

On this week’s Talking Michigan Transportation podcast, Jim Tymon, executive director of the American Association of State Highway and Transportation Officials (AASHTO), who participated in the event, talks about what the Interstate system has meant to the country and what could come out of the initiative.

The initiative will spur renewed conversation about the benefits of the system as well as some unintended consequences and focus on ideas for improvement.
