Market Street from Bowie Street to I-37 will close to all traffic on Saturday, September 14, 2013.
This closure will last for about 11 months for construction.
To travel to I-37 north, drivers will turn onto Bowie from Market, turn right onto Houston Street, turn left onto Live Oak Street and enter the entrance ramp after Nolan Street.
To travel to I-37 south, drivers will turn right on either St. Mary's or Alamo Streets, turn left onto Cesar Chavez Boulevard and turn right onto the entrance ramp.
"We are anticipating that people will be pretty confused for the first week or so, but hopefully after that, (they) will settle into the new routine and it will be like any usual traffic situation downtown,” said Melissa Sparks, the City of San Antonio's public relations manager.
Pedestrians will take a newly constructed pedestrian path on Commerce Street that runs under I-37, which also includes a bike path.
The pedestrian bridge that leads to the Alamodome is not available as parts of it have been demolished and are being reconstructed.
