NCTA narrows possible alignments on TriEx; but an endangered mussel may change route in Garner

Last week, the North Carolina Turnpike Authority eliminated three of the possible alternative routings for the southeastern extension of the Triangle Expressway.  The elimination of the Yellow, Purple, and Blue options come as a relief to residents of Holly Springs and Fuquay-Varina.  However, the dwarf wedge mussel - an endangered species - may alter the TriEx through Garner compared to the widely supported route proposal of 20 years.

Where the Orange Corridor, which has been on the books as the planned routing of the Southern Wake Expressway since the 1990's, crosses Swift Creek is near locations where the endangered mussel has been found.  The second option, known as the Red Corridor, crosses Swift Creek further north and the dwarf wedge mussel has not been known to habitat that section of the creek.

Even though the Orange Corridor has been the "protected corridor" for nearly 20 years, protected meaning that commercial and residential development has been limited on the prospective right of way, federal regulations require that other corridors be studied.

The Red Corridor would run further to the north and have a greater impact on existing homes, businesses, and planned development.  Garner leaders fear that the Red Corridor would cut the town in half.

This isn't the first time that the dwarf red mussel has impacted highways in North Carolina, specifically in the greater Raleigh area.  The US 70 Clayton Bypass was redesigned over Swift Creek and delayed a number of years on mitigation issues for the endangered mussel.  100 foot buffer zones were created to prevent environmental damage from chemical and oil sediment runoff into Swift Creek.

The concern over the Red Corridor and its possible impact on the town prompted Garner officials to hold a town hall meeting this evening in which a capacity crowd was expected.

The NCTA expects a route to be finalized by 2012.

Old US Route 60/70 through Hell (Chuckwall Valley Road and Ragsdale Road)

Back in 2016 I explored some of the derelict roadways of the Sonoran Desert of Riverside County which were part of US Route 60/70; Chuckwalla Valley Road and Ragsdale Road. US 60 and US 70 were not part of the original run of US Routes in California.  According to USends.com US 60 was extended into California by 1932.  US 60 doesn't appear on the California State Highway Map until the 1934 edition. USends.com on US 60 endpoints 1934 State Highway Map Conversely US 70 was extended into California by 1934, it first appears on the 1936 State Highway Map. USends.com on US 70 endpoints 1936 State Highway Map When US 60 and US 70 were extended into California they both utilized what was Legislative Route Number 64 from the Arizona State Line west to Coachella Valley.  LRN 64 was part of the 1919 Third State Highway Bond Act routes.  The original definition of LRN 64 routed between Mecca in Blythe and wasn't extended to the Arizona State Line until 1931 acc...

The last 1956-63 era California Sign State Route Spade?

Along southbound California State Route 170 (the Hollywood Freeway Extension) approaching the Hollywood Freeway/Ventura Freeway interchange a white California State Route 134 Sign State Route Spade can be observed on guide sign.  These white spades were specifically used during the 1956-63 era and have become increasingly rare.  This blog is intended to serve as a brief history of the Sign State Route Spade.  We also ask you as the reader, is this last 1956-63 era Sign State Route Spade or do you know of others?  Part 1; the history of the California Sign State Route Spade Prior to the Sign State Route System, the US Route System and the Auto Trails were the only highways in California signed with reassurance markers.  The creation of the US Route System by the American Association of State Highway Officials during November 1926 brought a system of standardized reassurance shields to major highways in California.  Early efforts to create a Sign State Route ...

Paper Highways; Interstate H-4 through downtown Honolulu

The Hawaiian Island of O'ahu is home to four Interstate Highways; H-1, H-2, H-3 and H-201.  Had history gone slightly differently during the 1960s a fifth Interstate corridor on O'ahu could have been constructed through downtown Honolulu and the neighborhood of Waikiki.  The proposed corridor of Interstate H-4 can be seen above as it was presented by the Hawaii Department of Transportation during October 1968 .   This page is part of the Gribblenation O'ahu Highways page.  All Gribblenation and Roadwaywiz media related to the highway system of O'ahu can be found at the link below: https://www.gribblenation.org/p/gribblenation-oahu-highways-page.html The history of proposed Interstate H-4 The corridor of Interstate H-4 was conceived as largely following what is now Hawaii Route 92 on Nimitz Highway and Ala Moana Boulevard.   Prior to the Statehood the first signed highways within Hawaii Territory came into existence during World War II.    Dur...
