BIG I-45 DOWNTOWN REROUTING, GRAND PARKWAY EXPANSION GET GO-AHEADS Yesterday was a big day for Houston freeway expansion and reconfiguration: On Tuesday, the Texas Transportation Commission gave the go-ahead for construction to begin in late 2020 on the first of 7 separate projects that will move I-45 from the west and south sides of Downtown to its east side, paralleling U.S. 59 behind the George R. Brown, reports Chron transportation writer Dug Begley. Separately, the commission also selected design and construction crews for the next segment of the Grand Parkway, from I-69 near New Caney to I-10 east of Baytown. How grand that section of the Grand Parkway actually ends up being may depend on your perspective: This segment of the Houston area’s fourth ring road is expected to cost $1.25 billion and open in 2022 — but the tollway will have only a single lane in each direction. [Houston Chronicle; previously on Swamplot] Diagram of I-45 rerouting: TxDOT
