OK, *if* the $$ was there right now for AR to finish I-49, how soon could what's left to do (Fort Smith-Texarkana, Ark. River bridge, Red River bridge, full 4-laning of the Bella Vista bypass) be built and opened?
Among other things,
this map illustrates the remaining sections of I-49 that are not under construction (red lines). The current gross estimate for completing everything is $2.8 Billion. This includes the river crossings (Arkansas River estimated around $500 million) and the remaining two lanes of the Bella Vista Bypass (estimated at $50 million). It does not include the first two lanes of the Bella Vista Bypass that are under construction; nor does it include those sections of the first two lanes that will be under construction as a result of the half-cent sales tax program.
It is important to note here the Bella Vista Bypass will not be completed as a two lane or a four lane facility until Missouri DOT is able to meet us at the state line. Through the years and during the course of this project’s development, there have been times when Arkansas was not ready to meet Missouri at the state line. Currently the bypass will be completed up to Benton County Road 34.
If the money were all of a sudden magically available as described in the original question quoted above, the planning estimates for the remaining sections would have to be updated. While the route (new alignment) is approved and environmental impact statements have been completed, design work has not been started.
Among the items to consider here include whether or not to divide the design into several projects that multiple consultants could tackle at the same time. Public meetings would be required. Purchase of right-of-way would be required. Not until all utilities are relocated would these projects be let to construction.
The amount of time it will take for a contractor to complete any of these projects will vary as it does on any other construction project. Depending upon how the job is set-up, a contractor’s bid may include the number of working days in which to complete the project. And then there are the river crossings…
Currently we are estimating 24 months for the U.S. Highway 70 (Broadway) bridge over the Arkansas River at Little Rock to be out of service while the old structure is demolished and the new one constructed. That is an estimate based on a fast-track schedule. A bridge over the Arkansas and Red Rivers on new location is not likely to be fast-tracked.
So how would this all play out if the money were available? While nothing is written in stone, it’s reasonable to assume that as money does come available, we would start by constructing bypasses around several of the communities along the route – Mena, DeQueen, Waldron, etc. Then as more money becomes available, we would begin to link those bypasses. Eventually we would have a highway.
As a comparison, consider the construction of I-540 between I-40 and the State Highway 265 interchange (Exit 60):
· 42 miles in length
· $459 million to construct (including $37.1 million for the twin tunnels)
· Let as 24 separate contracts
· Construction began in January 1987
· Construction completed in January 1999
All of the above was after design was finalized, after public meetings were held, after right of way was purchased, and after utilities were relocated.
