CNU Coalition Study Finds Restored Avenue Would Meet Traffic Needs, Stimulate Rebirth in New Orleans


Removing Claiborne freeway, restoring boulevard would add just minutes to trips and return blighted blocks to valuable use

As public and private partners in Greater Tremé and Lower Mid-City work to restore the Claiborne corridor to economic and cultural vitality — and as the Claiborne Expressway and its deteriorating ramps face up to one hundred millions of dollars in reconstruction— a new study of traffic data and circulation patterns concludes that removal of the freeway would bring important benefits for surrounding neighborhoods and New Orleans as a whole.

It concludes that the replacement of major segments of the Claiborne I-10 freeway with a restored urban boulevard would result in a well-functioning transportation system that meets regional needs  while promoting the economic and social rebirth of the once-vibrant Claiborne Avenue and its surrounding communities.

This study — commissioned by a local coalition dedicated to a brighter future for the corridor and conducted by the transportation engineering firm Smart Mobility — is the first detailed effort to assess the impact of the possible freeway removal that receives serious consideration in the city’s new draft Master Plan. At a development-oriented meeting last week, Mayor Mitch Landrieu said that the removal of the Claiborne Expressway deserved further attention and study.

The study uses  state traffic data to compare transportation system performance under both the current configuration and scenarios that would replace all or part of the freeway between the Pontchartrain Expressway and Elysian Fields Avenue.  It finds  that a boulevard and nearby surface streets would have ample capacity to absorb and efficiently move traffic in the absence of the freeway. The majority of drivers who use the Claiborne for short trips would see minimal increases in travel time and benefits from fewer surface street obstructions. Even those using the freeway for longer trips would see small increases in travel times, just 2-3 minutes under one scenario and 3-6 minutes under another that would replace a longer stretch of freeway.

“From a technical perspective, the data and analysis show that Claiborne doesn’t need to be a freeway,” said John Norquist, CEO of the Congress for the New Urbanism, a coalition partner that received funding from the Ford Foundation and the National Endowment of the Arts. for the report. “And from a redevelopment perspective, as a boulevard, it instantly becomes a vastly more valuable and vital setting for economic and cultural activity.”

After briefings with city officials over the past two days, the partners who commissioned the report — the Claiborne Corridor Improvement Coalition of the NEWCITY Neighborhood Partnership — are releasing the study today. It is available for download at CNU CEO John Norquist, transportation engineer and report co-author Lucy Gibson, Urban Design Research Center President and CEO Clifton James and other coalition partners will be available for media interviews today, Thursday, June 22.

This report builds on planning efforts stretching as far back as Clifton James’ and Dr. Rudy Lombard’s 1976 “Claiborne Avenue Design Team Report,” commissioned by the Louisiana Department of Highways. It also strengthens the case for the next needed step: a comprehensive engineering study of formal plans to replace segments of freeway and restore the boulevard, as recommended in the draft of the New Orleans Master Plan. That study would involve coordination among the City of New Orleans, the Regional Planning Commission and the Louisiana Department of Transportation.

Demolition of the aging elevated expressway would remove an eyesore that has dominated and damaged the Tremé/Lafitte landscape for almost 50 years and held back serious attempts to spur economic development. The destruction of the oak-lined avenue and construction of the elevated expressway in the 1960s, was intimately tied to the overall decline of Claiborne’s surrounding neighborhoods and occurred against the wishes of the area’s largely disenfranchised African-American residents. Removing the elevated expressway would free up more than 50 acres for use as public neutral ground, bike paths, transit corridors, as well as freeing significant acres outside the boulevard itself for redevelopment. In addition, a simplified interchange between the restored Claiborne boulevard and the Pontchartrain Expressway could free up valuable land near the Superdome for redevelopment.

“Restoring this vital corridor would provide economic opportunities to a diverse group of New Orleanians,” said coalition chair Vaughn Fauria, Executive Director/President of NewCorp, Inc., “so we must come together to decide how best to seize this opportunity.”
The report’s chief findings include:

  • A small fraction of drivers — less than 20 percent — use the Claiborne Expressway as a through route between the east and west portions of the region and beyond. With most through traffic using I-610, the Claiborne I-10’s “use does not match the intended function of an interstate highway,” concludes the report.
  • The average trip length on the Claiborne Expressway is a mere 1.6 miles, according to the DOT’s regional model, suggesting many drivers use it as a short-cut between nearby neighborhoods.
  • For the minority of users traveling the full length of the elevated expressway over  Claiborne, trips would lengthen by two to three minutes (off-peak and peak) under an alternative that would convert the freeway segment between Canal and St. Bernard to a boulevard, according to a review of the region’s travel-demand base model. Under an alternative involving removal of the freeway from Canal to Elysian Fields, travel times would lengthen by 3 to 6 minutes.
  • For the larger number of users connecting to destinations such as Louis Armstrong Park, the French Quarter and downtown, connectivity would improve with a boulevard and improved street connections.
  • Although a highly connected surface street network is a hallmark of the New Orleans system, street closures in the area over the years have actually reduced street connectivity. Removal of the Claiborne Expressway could be a catalyst to reconnect streets such as Galvez across the Pontchartrain Expressway, relieving Claiborne Avenue of its role as a primary connector between uptown and downtown.
  • Traffic on both the Claiborne Expressway and nearby streets are substantially below pre-hurricane levels, “indicating that the capacity is available to absorb redistributed traffic” resulting from the freeway’s removal, say the study’s authors.
  • The Claiborne Expressway is not a hurricane evacuation route designated for contra-flow traffic. It serves a role as a collector during times of evacuation but this function could be served better by a surface boulevard.

“This study  says that you could tear down the I-10 and not only would New Orleans be fine–it would be better,” said Jack Davis, President, Smart Growth for Louisiana

NEWCITY and the Claiborne Corridor Improvement Coalition hope that this report will inform public dialogue about the Claiborne I-10 elevated expressway and demonstrate the need to pursue the comprehensive study. “More than the take down of the expressway, we are really advocating for the rebuilding of Claiborne Avenue and all the communities it touches,” said founding coalition member James R. Kelly, President & CEO, Providence Community Housing.
