Details of the NC68/US 220 I-73 connector

NCDOT was gracious to send me their plans of the proposed NC 68/US 220 Connector that will one day carry Interstate 73. The blog's Bob Malme also attended tonight's public workshop and was able to get additional details on the project and will be included below.

First, the entire project is 13 miles in length and will consist of three segments. The connector, which will be built totally on a new alignment, is approximately 8.5 miles in length and will be built to Interstate standards and a 70 mph design speed. Previously, it was thought that the road would be built just short of Interstate grade and upgrades made over time, but that is no longer the case.

The Connector itself is broken down into two sections (A & B). Going west(South I-73) to east (North I-73), there will be interchanges at NC 68, NC 150 in Summerfield and US 220.

Under the original plan, Interstate 73 was to follow NC 68 South to Interstate 40. But those plans have changed, I-73 will briefly bump NC 68 before turning south and east to connect with Bryan Blvd. near Piedmont-Triad International Airport. From there, I-73 will follow Bryan Blvd. until joining the Greensboro Urban Loop/I-840.

The change to the routing of I-73 has drastically changed how I-73 intersects NC 68. The new plans have the NC 68/I-73 interchange that will include flyovers that will carry I-73 South traffic over NC 68 as it heads towards Bryan Blvd.

Bob, who was able to see much larger versions of the plans in person, explains, "[I-73] from Bryan Blvd. will meet NC 68 south of the Connector, but they probably won't run together more than half a mile northbound and less southbound where a flyover ramp will take I-73 over NC 68 in the vicinity of today's Sedgefield Road intersection and have it merge about a 1/4 mile further south. The part of NC 68 that will be I-73 and the Connector will be built to 70 MPH/Interstate standards with 2 lanes in each direction."

Figure 3. The I-73 Connector continues east towards US 220. I-73 North will run left to right. (Larger pdf file accessible here.)

The connector ends at a partial interchange with US 220 just south of the Haw River. Bob describes the partial interchange, "The interchange will feature a flyover for US 220 South which will go over the river and I-73 as it turns right onto the Connector, there will be no access from US 220 North to I-73 South, I-73 North will just meet 220 on its current path."

Figure 4. After a diamond interchange with NC 150, the connector ends with a partial interchange with US 220 as I-73 turns north. (Larger pdf file accessible here.)


From there, Section C of the project begins. Section C will build a four lane limited access highway northwards paralleling the current two lane US 220. The project length is 4.5 miles and is currently built to a 60 mph design speed. According to Bob's discussions with Section C project engineers this evening, "Since no federal money is [currently] involved, it will be built as initially as a 60 MPH speed limited access highway, with interchanges for NC 65 and US 158 (which already exists) and NC 68 at the northern end (could not tell if you could access 68 from north I-73). They hope to get federal funds once the Connector construction is underway in 2014 to upgrade the road to interstate status by the time the Connector is finished around 2017."

Construction on the connector is scheduled to begin in 2014 with completion by 2017.

I think you ment NC-68 instead of I-68. lol.

Thanks! Blogging so much that I-68 and NC 68 starts to run together!

California State Route 77; the real "Shortest Signed" State Highway

Over the last two weeks I visited almost every State Highway in the San Francisco Bay Area.  The shortest State Highway by a large margin in the Bay Area is California State Route 77.


CA 77 is presently only 0.45 miles in length and is located entirely within the City of Oakland.  CA 77 begins at Interstate 880 and heads eastward on 42nd Avenue to CA 185 on 14th Street.  As presently completed CA 77 would rank as the third shortest State Highway only behind CA 275 and CA 283.

CAhighways.org list of Shortest State Highways

CA 77 presently has a 13.4 mile portion that has not been constructed.  CA 77 as originally envisioned would have continued northeast towards Concord and would have junctions with; I-580, unbuilt CA 93, CA 24, I-680 and CA 242.  According to CAhighways.org the present route of CA 77 was designated as Legislative Route Number 233 which was approved by the State Legislature in 1953.  The legislative description of LRN 233 was changed to LRN 235 by 1957.

Local Sign Find - Georgia Route 280 found in Sutersville, PA?

Sign errors happen - a US shield in place of a state highway shield or vice versa.  It's interesting to some and a pet peeve to others.  But when Mike Natale found a Georgia 280 shield in Sutersville, Pennsylvania, you have to think something must be up.
And in this case, there's a reason for it.  It's a prop for a television series.  Netflix's popular TV series "Mindhunter" is shot in the Pittsburgh area.   Mike came across the GA 280 sign in October 2018 and it is possible that the scenes involving Georgia 280 should be in Episode 6 or 7.

Georgia State Highway 280 is located in northwestern and western Atlanta.  That's a far cry from the Mon Valley.  It is common for television or movie scenes to be shot elsewhere than where they are set at.  However, it is very rare to see a sign prop out in the wild while production is on going.  This is a great find by Mike!

The strange evolution of Interstate 280 in San Francisco

Recently while in the San Francisco Bay Area I wanted to check out the north terminus of Interstate 280 in downtown San Francisco.  I-280 as currently aligned diverges significantly from what was originally planned in the City of San Francisco.


Much of the finalized planning of the Interstate Highway System in the San Francisco Bay Area was largely plotted out by 1956.  Between CA 17 in Los Gatos and CA 1 in San Francisco the path of I-280 ultimately followed Legislative Route Number 239 which was designated by the State Legislature in 1957.

LRN 239 can be seen appearing on the State Highway Map City Insert of San Francisco connecting to CA 1 by 1958.

I-280 was to take a far different route than it currently does in San Francisco.  The original plan for I-280 was to follow CA 1 on LRN 56 towards the Golden Gate Bridge where it would terminate at I-480/LRN 224 and US 101.  The original planned alignment of I-280 becomes apparen…
