PTI
Airport ConnectorPossible number for proposed freeway that would run from I-73/Bryan
Blvd near PTI Airport to split of I-40 and Business 40 west of
Greensboro, or for an alternate proposal (the I-73/74 Connector) that
would run the highway from Bryan Blvd. at NC 68 to the I-74
Winston-Salem Beltway (if both parts are built the part running from the
I-73/74 Connector south to I-40, (called the 'I-40 Connector' in some
proposals) could get another number). The I-73/74 Connector
proposal was added to the NCDOT State Transportation Improvement Program
(STIP) in November 2005 for environmental and planning purposes only. It
was then under study by the North Carolina Turnpike Authority for a
short period as to whether it could be built as a toll road. Apparently
this proved unfeasible, and is no longer listed as a NCTA proposal. The
proposed highways can be seen in this map courtesy of the Winston-Salem
Journal:

Interstate 193 - Braintree to Cape CodYes, this is not a North Carolina route, but one from my home state of Massachusetts. The proposed designation for current MA 3 between I-93 in Braintree and US 6 at the Sagamore Bridge in Bourne. If one can take an interstate spur from Providence, RI to Cape Cod why can't drivers from Boston to the Cape? Besides, doesn't America's Hometown (Plymouth) deserve its own interstate?
