Baton Rouge Traffic: $1B 'Bump' Bypass or $140M Fix?
If you were stuck on I-10 last month when that overturned 18-wheeler backed up traffic in Baton Rouge for nearly 10 hours, you are not alone, and you are not the only one still talking about it. That jam just brought a big, old idea back to the table: a roughly one billion dollar bypass people call "the bump." But not everyone thinks it is the right fix. Here is the quick version in my video, and the full breakdown below.
More on living in Baton Rouge.
What happened: DOTD puts "the bump" back on the table
On Tuesday, Oct. 21, the Louisiana Department of Transportation and Development (DOTD) presented new proposals aimed at easing traffic, and one of them is the Baton Rouge bypass, better known as "the bump." According to WAFB's reporting, the plan would use the U.S. 190 bridge, add new connectors, and build a new bridge near Plaquemine.
The timing is no accident. That nearly 10-hour backup on I-10 last month got state lawmakers and DOTD talking, and the bump is now one of the options being considered.
DOTD Secretary Glenn Ledet said the department is working on a large I-12 corridor study that looks at the I-10/I-12 split in the capital region and at adding capacity along the corridor. The bump is part of that analysis. Ledet noted the idea has been discussed for a long time and that DOTD is looking for ways to move it forward. Other big projects on DOTD's list include a new Mississippi River bridge and continued I-10 widening.
The other side: a cheaper fix on Airline Highway?
Not everyone is sold. Coleman D. Brown, who chairs the infrastructure committee for the East Baton Rouge Parish Chamber of Commerce, says the bump is not new and is not needed. He says DOTD turned the project down 11 years ago.
His alternative: widen Airline Highway to six lanes and synchronize the traffic lights. Brown points out that voters approved the Airline Highway widening back in 2018 with 61% of the vote, and he says the project has been delayed for eight years.
The key numbers
Nearly 10 hours: how long traffic backed up after last month's I-10 wreck
About $1 billion: Brown's estimate for the bump
About $140 million: Brown's estimate for widening Airline Highway and syncing the lights
Roughly 1/8 the time: how much faster Brown says his plan would solve the problem
61%: voter approval for the Airline Highway widening in 2018
No date yet: DOTD has not set a final decision timeline or cost estimate for the bump
One important note: the cost and timing figures above come from Brown, not from DOTD. DOTD says its analysis of the bump is still ongoing.
Why it matters if you live (or want to live) around Baton Rouge
Here is where my realtor hat comes on. When people decide where to buy a home in the Baton Rouge area, the commute is almost always part of the conversation. How long it takes to get from Ascension, Livingston, West Baton Rouge or the south side of town to work, school and the rest of daily life can shape which areas buyers look at.
Big road decisions like this one can influence traffic patterns for years. A new bridge and bypass near Plaquemine, or a wider Airline Highway with synced lights, could each change how people move around the region in different ways. Nothing has been decided, and I am not here to predict prices or pick a winner. But if you are planning a move, a purchase or a sale over the next few years, this is the kind of story worth keeping on your radar.
Brown also encouraged Airline Highway property owners in particular to show up to DOTD's public meetings, saying he believes many of them are not aware of the plans.
What to watch next
DOTD's quarterly public meetings: DOTD plans to hold them to keep the public informed. This is your chance to hear the details and ask questions.
The I-12 corridor study: the bump analysis is part of it, so updates on the study will tell us a lot.
A cost estimate and decision date: neither has been set yet.
Airline Highway: whether the voter-approved widening moves forward.
