Two competing plans for the Evangeline Thruway corridor have new Mayor-President Monique Blanco Boulet at odds with the city’s Evangeline Thruway Redevelopment Team over how to protect pedestrians on the parish’s most deadly roadway.
The central difference in the plans — displayed by DOTD at public showcases in April — comes down to this: traffic signals versus roundabouts.
A seemingly small variation in the scale of the estimated $2 billion I-49 Lafayette Connector project, the options are polarizing stakeholders with opposing visions for improving pedestrian safety in the future corridor, particularly along a boulevard imagined as a feature that would repair damage done to historic neighborhoods in Lafayette’s city center.
Boulet has made completing I-49 through Lafayette a priority, despite her government’s limited power over the federal project. The Connector has been under development in one form or another for nearly 40 years. Tens of millions have been spent on its design and right of way purchases.
State planners aim to have yet another design federally approved by early 2025, after the project’s alignment and design were changed in the years since the 2003 record of decision defining the Connector’s contours was produced.
Among those changes was the conversion of a spur of the Evangeline Thruway into a boulevard that would mend some of the neighborhood fabric split by that highway’s construction in the mid-20th century. In concept, the boulevard would make space for new businesses and homes to sprout at the street level while the interstate zoomed above on an elevated span.

Boulet’s team favors roundabouts to control traffic on that boulevard. And that support has elevated it to become DOTD’s “preferred alternative,” which could weigh heavily in the design ultimately greenlit by federal officials.
“Roundabouts are traffic calmers. They bring everybody to 15 miles per hour. If you get hit at 15 miles per hour as opposed to 40 miles per hour, it’s a game changer. You might have a little whiplash, but you’re not going to lose a leg. It’s a traffic calmer, and you can mitigate for pedestrians,” says Boulet, who has been involved in the I-49 Connector project for years during her time atop the Acadiana Planning Commission.
Traffic signal proponents argue roundabouts aren’t safe enough because they don’t force cars to stop and thus won’t offer pedestrians dedicated opportunities to cross the roads.
Roundabouts have become increasingly popular across the U.S. since the late 1990s, with many state transportation agencies and metro areas investing in the concept as means of reducing fatalities in car crashes. Research broadly supports roundabouts’ safety records. Lower speeds lead to fewer deaths and less severe injuries.
But those benefits largely depend on how the roundabouts are designed and where they are placed. Smaller, one-lane roundabouts are often compatible with pedestrian-friendly streets. That’s less true as more lanes are added and traffic counts increase, according to the highway research arm of the National Academy of Sciences.
As proposed, the roundabouts rotate two lanes — merging two pairs of two lanes going in either direction — at three junctions, including one at Jefferson Boulevard, just east of the Connector’s bridge span and Downtown.
In 2022, the Evangeline Thruway Redevelopment Team, created by Lafayette’s former City-Parish Council to advise LCG on community impacts and visions for the massive project, approved a nine-page report questioning the value of urban roundabouts for the future grand boulevard, which would carry local, at-grade traffic along the footprint of the existing northbound lanes of the Evangeline Thruway.
Last week, members of the team’s project subcommittee again criticized the idea, saying it had repeatedly been panned by public feedback.
“It just comes back to the fact that when the Thruway was put in, it created a barrier of connection between one side of the community and the other side of the community and that this is kind of like the one opportunity that we have to make sure that people can easily cross from one side to the other on foot or bike or car,” said ETRT member Brady McKellar during the meeting. “And when we’re talking about roundabouts, we go back to the emphasis on the car and not on the emphasis of serving the community.”
Go deeper on I-49
Short on splashy projects, the budget, introduced to the councils this week, focuses instead on LCG’s financial plumbing.
In town halls held this week, economic development emerged as the central tenet of incoming M-P Boulet’s vision for Lafayette.
Incoming M-P Boulet is holding three town hall meetings next week to gather input from the public on a trio of key local issues.
That’s a critical point of contention because of planned developments and investments in the corridor that aim to take advantage of its proximity to Downtown and the future relocation of interstate traffic to elevated overpasses.
Roundabout opponents say those improvements in pedestrian access and safety could be lost by letting a critical design decision err on the side of streamlining car traffic.
“I do not prefer roundabouts because they are not pedestrian friendly; in fact they encourage drivers to drive faster because now you are not allowing the pedestrians an opportunity to cross because the traffic is continuously flowing around the roundabout,” says Nureaka Ross, who founded Protect Our Pedestrians in 2022 to advocate for better road safety measures and pedestrian prioritization along Lafayette’s major roadways where pedestrian fatalities have been prevalent.
Between 2020 and 2022, at least a dozen people were killed by cars while walking along or across the Evangeline Thruway. Project opponents and advocates alike have pointed to the dangerous conditions on the ground and stress the urgency of completing or canceling the Connector itself, even as the project has dragged on over the decades.
Debating the merits of roundabouts and traffic signals on the boulevard points back to the essential dispute about the urban highway project. For those opposing roundabouts, like pedestrian advocate Ross, it’s about who the project is fundamentally for.
“The way it’s designed is to move cars faster,” she says. “It prioritizes cars, not people.”

Why does it need to be one or the other? Roundabouts can be signalized.
Also, placing elevated pedestrian crosswalks (with LEDs on signs and across crossing) further back from the intersection can help to make roundabouts safer for pedestrians. In many cases, it feels more natural to cross the street away from the intersection. Have there been any recorded studies of the current pedestrian traffic flows? That would tell you the best place for pedestrian crossings.
Considering that the final Preferred Alternative does utilize the ETRT's desired concept of signalized intersections along the new "grand boulevard" concept everywhere except for the downtown/Second/Third/Simcoe connections, and that it satisfies a significant objective of maintaining at least an indirect through connection of Simcoe Street via Second and Third, I really fail to see why there is so much debate over this attempt at balancing traffic flow, connectivity, and accessibility for pedestrians and bicyclists. The exit from elevated I-49 to/from the north to this menage isn't really that busy save for rush hour mornings and afternoons, and there will still be plenty of spaces where pedestrian and bicycle traffic can avoid major conflicts.
This still sounds to me like another ruse to stall and manufacture opposition to this entire project until a new Teche Ridge-type east bypass or the LRX loop is invented and offered by the usual NIMBYs to kill the Connector freeway project once and for all. Very unfortunate, because of all the efforts made and refinements done to design this absolutely overdue and critically needed project to better mesh with the surrounding neighborhoods and incorporate multimodal transportation models currently absent on the current deathtrap that is the Evangeline Thruway. Hopefully, cooler heads will prevail and we can focus on funding and construction of the Connector freeway; it is already way past overdue.
