Plans to widen Highway 226 to a four-lane route from U.S. 67 east to U.S. 49 consisted of upgrading existing Highway 226 to an at-grade route and building a south bypass of Cash. This widened stretch ties into a new 1.8-mile alignment (Highway 49 Connector) from Highway 226 southeast to U.S. 49 at Gibson. Originally the chamber of commerce requested that the corridor be freeway-grade, but the route was built at-grade instead.
A five section project involved upgrading Highway 226 to a four-lane corridor. The sections were completed as follows:2,3
- October 2012 – 4.0 miles of Highway 226 completed from U.S. 67 east to the Cash Bypass at a cost of $15 million.
- Late 2015 – 1.6 miles of Highway 226 along the Cash Bypass at a cost of $6.3 million.
- Late 2015 – 5.1 miles of Highway 226 from the Cash Bypass east to the Highway 49 Connector at a cost of $45.3 million.
- June 23, 20164 – 1.7 miles of the Highway 49 Connector from Highway 226 southeast to U.S. 49 at a cost of $18 million.
I-730 was never approved by AASHTO, and furthermore was premature as Interstate 30 was not assigned to the U.S. 67 freeway (I-57 was formally proposed for the route in 2016).
