Relieving one of Houston’s worst bottlenecks will come with some lengthy complications for northbound drivers on Interstate 45 headed into Houston’s central business district, starting Friday night.
After years of delay, work is starting on a modification to Spur 5, the ramp that connects northbound I-45 traffic to downtown via Pease and St. Joseph. The spur is being rebuilt to also be the connection from northbound I-45 to Interstate 69, also U.S. 59 in the Houston area.
Though it is a major improvement, the work means seven months of construction detours for downtown-bound drivers, according to the Texas Department of Transportation. Crews will close Spur 5 at Scott Street starting at 9 p.m. Friday, so they can demolish the ramp parallel to I-45.
In the interim, drivers that would normally use the spur will exit at Scott and use the I-45 frontage road to travel into downtown. More than 13,000 vehicles use Spur 5 to access downtown at St. Joseph, according to a 2015 TxDOT traffic count. More than 200,000 vehicles use I-45 in the area.
In addition to affecting downtown-bound traffic, the spur closure means drivers won’t be able to access northbound I-45 at Scott Street, said Deidrea George, spokeswoman for TxDOT in Houston.
The interchange work is hardly the end of construction along the I-45 corridor around downtown, with many considering it a precursor to potentially a decade of constant construction. TxDOT is proceeding with plans to realign I-45, I-69 and the interchange with Texas 288 as part of a $3 billion redesign of the downtown freeway network.
The first of seven projects to rebuild interchanges, widen the freeways and shift I-45 to run parallel to I-69 along the east side of downtown is scheduled to begin in 2020, about a year after the Spur 5 work is set to finish.
Allen said the Spur 5 project is being designed with the future interchanges in mind, but will require some minor modifications once I-45 moves.
This has been in the works for awhile – we first heard about it in 2014, long enough ago that I had about given up in searching my archives for something I knew I had posted about because I was sure it had been more recent than that. This construction is part of the grander plan for redoing I-45, though it would probably be worth doing on its own if that doesn’t materialize. Whatever the case, it’s going to suck. I pity anyone who will have to deal with it. The Press has more.
