Who you callin' useless?

What do all these roads have in common?

US 264 in Wake County
US 258 in Onslow County
US 117 in Wilson County
US 311 in Rockingham County
NC 39 in Johnston County

They all have what roadgeeks call "useless multiplexes" -- a road that ends at a random point while sharing pavement with another road, and North Carolina seems to have more useless multiplexes than most states. For example, 264 east of Raleigh is routed along the US 64 freeway between Zebulon and the Beltline, but at the Beltline 264 ends while 64 continues. Why couldn't 264 just end at 64 in Zebulon where the two roads merge? (And to make it even more ridiculous, that's exactly what it did until about 1995!)

I think I finally figured out why these useless multiplexes exist, and they most certainly aren't useless. Look at a map and you'll notice that all of these roads go somewhere -- or, more to the point, they connect two places. And it makes it a hell of a lot easier to give directions when you only have to follow one road.

For example, do you need to head from Raleigh to Wilson or Greenville? Take US 264. Coming south on I-95 and need to get to Goldsboro? US 117's your ticket. US 258 connects Jacksonville and Kinston, and US 311 does the same between Winston-Salem and Eden (or it would if the signage would catch up with the map). Traffic that's going between those cities probably doesn't care that the road they're following is also US 64, 264, NC 24 or NC 135, much the same that traffic on I-85 from Charlotte to Durham doesn't care that I-40's also on the road for 40 miles or so.

It doesn't apply to absolutely everything. The formerly- (and still largely-) useless multiplex of NC 24 and 27 connects so many different places to Charlotte that it's pretty pointless; the only people that would use one road but not the other would be NC 24 traffic from Fayetteville to Charlotte, all 141 miles of it. Likewise, I'm not sure too much traffic heads from Eden to...well, wherever NC 700 ends, and NC 902 in Chatham County literally connects Pittsboro to nowhere. But overall, those useless multiplexes might not be so useless the next time you have to give directions to someone who does best only following one road.

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
