I-73 takes another big step forward in South Carolina

Yesterday, two major developments in I-73's eventual construction occurred in South Carolina.

First, SCDOT narrowed the studied alternatives to the highway. Basically it is down to two possibilities. One follows and uses most of US 501 from Marion to SC 22. The highway would use part of the US 301 Marion Bypass, jump on to a new alignment, return to US 301 north of Galivants Ferry around SC 41 and then the road leaves US 501 to bypass Galivants Ferry and Aynor. South of Anyor the road uses US 501 until SC 22 and then follows the Conway Bypass to its end.

The Second is a new path alignment that runs north of the US 501 Option. It runs closer to Mullins (bypassing the town to the south) and reaches SC 22 near the SC 319 interchange.

There are crossovers between the two main alternatives, so a hybrid of both options may be the final routing. What is also intersting is that both options cross I-95 north of SC 38, which is the current consensus for the north segment of the highway.

To see the corridors in detail go here:

The next big chunk of news is that the Toll consideration for the highway is pushing forward. The bills introduced have been fast tracked and will bypass going to committee. A vote could be early as NEXT WEEK.

Although the bills do not mention the amount of a toll or where the booths would be placed - that would be up to the DOT - there are some more details given. Tolls would be reduced for local residents perhaps by way of a pass system.

Thoughts:

First on the new alignmnet alternatives: As the picture gets clearer on where I-73 may go, some predictions can be made. The state knows that using the existing US 501 corridor with upgrades will be cheaper to build. So look for US 501 on all or parts of the route. The key is the influence of Mullins, which really wants the highway to be near it. Also, how close of an impact will Anyor want I-73 to have. I do think that the state will pick the northern alterntive to Mullins and use the crossover to US 501 near SC 41 and follow US 501 down to SC 22.

As for the tolls, nothing has been said about some concerns about wanting to create a SC turnpike Authority vs. just slapping tolls on the road through SCDOT. The political debate and the eventual vote will be the determining factor on that.

Thanks for keeping us all up-to-date on the I-73 saga.

Paper Highways: The Unbuilt New Orleans Bypass (Proposed I-410)

  There are many examples around the United States of proposed freeway corridors in urban areas that never saw the light of day for one reason or another. They all fall somewhere in between the little-known and the infamous and from the mundane to the spectacular. One of the more obscure and interesting examples of such a project is the short-lived idea to construct a southern beltway for the New Orleans metropolitan area in the 1960s and 70s. Greater New Orleans and its surrounding area grew rapidly in the years after World War II, as suburban sprawl encroached on the historically rural downriver parishes around the city. In response to the development of the region’s Westbank and the emergence of communities in St. Charles and St. John the Baptist Parishes as viable suburban communities during this period, regional planners began to consider concepts for new infrastructure projects to serve this growing population.  The idea for a circular freeway around the southern perimeter of t

Hernando de Soto Bridge (Memphis, TN)

The newest of the bridges that span the lower Mississippi River at Memphis, the Hernando de Soto Bridge was completed in 1973 and carries Interstate 40 between downtown Memphis and West Memphis, AR. The bridge’s signature M-shaped superstructure makes it an instantly recognizable landmark in the city and one of the most visually unique bridges on the Mississippi River. As early as 1953, Memphis city planners recommended the construction of a second highway bridge across the Mississippi River to connect the city with West Memphis, AR. The Memphis & Arkansas Bridge had been completed only four years earlier a couple miles downriver from downtown, however it was expected that long-term growth in the metro area would warrant the construction of an additional bridge, the fourth crossing of the Mississippi River to be built at Memphis, in the not-too-distant future. Unlike the previous three Mississippi River bridges to be built the city, the location chosen for this bridge was about two

Memphis & Arkansas Bridge (Memphis, TN)

  Like the expansion of the railroads the previous century, the modernization of the country’s highway infrastructure in the early and mid 20th Century required the construction of new landmark bridges along the lower Mississippi River (and nation-wide for that matter) that would facilitate the expected growth in overall traffic demand in ensuing decades. While this new movement had been anticipated to some extent in the Memphis area with the design of the Harahan Bridge, neither it nor its neighbor the older Frisco Bridge were capable of accommodating the sharp rise in the popularity and demand of the automobile as a mode of cross-river transportation during the Great Depression. As was the case 30 years prior, the solution in the 1940s was to construct a new bridge in the same general location as its predecessors, only this time the bridge would be the first built exclusively for vehicle traffic. This bridge, the Memphis & Arkansas Bridge, was completed in 1949 and was the third
