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.

California State Route 232

This past month I drove the entirety of California State Route 232 in Ventura County. CA 232 is an approximately 4 miles State Highway aligned on Vineland Avenye which begins near Saticoy at CA 118 and traverses southwest to US Route 101 in Oxnard.  The alignment of CA 232 was first adopted into the State Highway System in 1933 as Legislative Route Number 154 according to CAhighways.org. CAhighways.org on LRN 154 As originally defined LRN 154 was aligned from LRN 9 (future CA 118) southwest to LRN 2/US 101 in El Rio.  This configuration of LRN 154 between CA 118/LRN 9 and US 101/LRN 2 can be seen on the 1935 California Division of Highways Map of Ventura County. 1935 Ventura County Highway Map According to CAhighways.org the route of LRN 154 was extended west from US 101/LRN 2 to US 101A/LRN 60 in 1951.  Unfortunately State Highway Maps do not show this extension due to it being extremely small. During the 1964 State Highway Renumbering LRN 154 was assigned CA 232.  Of n

Former US Route 50 and the South Lincoln Highway from Folsom east to Placerville

The corridor of Folsom of Sacramento County east to Placerville of El Dorado County has been a long established corridor of overland travel dating back to the California Gold Rush.  The Folsom-Placerville corridor was once part of the path of the Lake Tahoe Wagon Road which became the first California State Highway and later the South Lincoln Highway.  In time the South Lincoln Highway's surface alignment was inherited by US Route 50.  The Folsom-Placerville corridor also includes the communities of; Clarksville, Shingle Springs and El Dorado. Part 1; the history of the Lake Tahoe Wagon Road, South Lincoln Highway and US Route 50 through Folsom-Placerville Folsom is located on the American River/Lake Natoma of eastern Sacramento County.  That lands now occupied by the City of Folsom were part of Rancho Rio de los Americanos prior to the finding of gold at Sutter's Mill during 1848.  During the California Gold Rush the lands of Rancho Rio de los Americanos were purchased by Jose

US Route 101 through Gaviota Pass

US Route 101 in the Santa Ynez Mountains of Santa Barbara County, California passes through Gaviota Pass.  Gaviota Pass is most well known for being part of El Camino Real and the namesake Gaviota Tunnel which opened during 1953.  Since 1964 Gaviota Pass and US Route 101 have also carried a multiplex of California State Route 1.   Part 1; the history of the Gaviota Pass corridor Gaviota Pass is historic path of travel through the Santa Ynez Mountains of Santa Barbara County.  Gavoita Pass was a known route through the Santa Ynez Mountains which was utilized by the Chumash tribes before the arrival of Europeans.  Gaviota Pass was first explored by Spanish during the 1769 Portola Expedition of Las Californias.  The Portola Expedition opted to follow the coastline northward fearing that the established Chumash path through Gaviota Pass was too narrow to traverse.  In time Gaviota Pass became a favored established path of Spanish travel which bypassed the hazardous coastline as part of El
