I'm sure it's no surprise for those who, like me, watched Bridges Coalition spokesperson Kay Stewart on the local news last week inexplicably announcing that there's a consensus in favor of two Ohio River bridges just minutes after a Louisville Metro Council committee held its first meeting to explore alternatives, but the Coalition hasn't been exactly forthcoming with relevant information.
The first clue may have been the council chambers shown overflowing with 8664 supporters, but the second was the testimony of veteran traffic engineer Walter Kulash, who last night, along with advocates Tyler Allen and J.C. Sites, shared his feasibility study with an enthusiastic group of citizens in the Bomhard Theater at The Kentucky Center for the Arts.
Some highlights:
*It's the proposed expansion of Spaghetti Junction to over 20 lanes (dubbed Fettucini Junction by an attendee as it's way too fat to be spaghetti) that's radical, not the 8664 proposal.
In searching the entire country, Kulash could only find one project similar in size and complexity to the Spaghetti Junction expansion on the Bridges books. It's in the Los Angeles metro area. Downtown freeway removal, though, is common. Portland, San Francisco, Milwaukee, and Chattanooga have all done it successfully. There's a current initiative in Portland to remove a second water-blocking freeway.
Other numerous, similar projects are in various approval and planning stages around the country with traffic models proving their meddle. Some were redesigned after initial planning as engineers began to figure out the advantages of smaller, surface level parkways over freeways.
* Fears of more endless studies and project delays are overblown. Even though much has been made by Bridges advocates of the dire consequences of trying to amend a federal record of decision, it just isn't that big of a deal. Kulash quoted an engineering friend who said that most major transportation projects in the country are operating under an amended ROD.
The initial approval process to reach a record of decision is made up of five steps that take years to complete. However, changes in plans require two questions to be answered: Does the changed proposal meet the purpose and need addressed by the original project and, if so, does it do so within the original project footprint so as to not further disturb the environment? If the answers are yes, all the original steps can be skipped and the record of decision can be amended in a matter of months. Kulash's work shows the answers to both questions are yes.
* Using numbers from the existing environmental impact study done for the Bridges Project, Kulash was able to show that the 8664 plan can handle the same traffic volume as the current proposal. Spaghetti Junction, greatly simplified under 8664, will have more than ample capacity to meet the peak hour, peak direction, year 2025 projections outlined in the Bridges study.
Waterfront traffic on I-64 was estimated by the Bridges project study to reach 100,000 ADT (average daily traffic) in the year 2025. 8664 would reroute 20,000 ADT to the northern, Indiana loop, leaving 80,000. The riverfront parkway would handle 40,000 to 50,000, leaving 30,000 to 40,000 ADT for the existing street grid. The east-west grid in and around downtown currently has 174,000 ADT in spare capacity, four to six times what's needed.
* Besides the obvious reclamation of riverfront property (valued between $130 and $260 million in real dollars, incalculable as a centerpiece), areas within sight or easy walking distance (calculated at 1/4 to 1/2 mile based on the experiences of other cities) would be greatly enhanced in value. Using the two mile stretch of the current waterfront 64 as a measuring stick, that equates to 300-600 acres or 60-120 city blocks.
* 8664 costs half as much as the current Bridges Project proposal and can be built faster.
