Major roadwork is scheduled to begin downtown Monday as part of the Market Street Realignment project.
The city will close the Interstate 37 south entrance ramp on Market Street.
All traffic will be diverted south to Tower of the Americas Way, and drivers can get on I-37 south using the entrance ramp just past Cesar Chavez Boulevard.
The city does not expect any other ramps to be affected.
The Market Street Realignment Project will redesign Market Street to run parallel with Commerce Street.
The work will create a pedestrian walkway on Commerce Street under I-37 with access to the Alamodome and surrounding restaurants and hotels.
The city also plans to install new sidewalks, bike lanes, traffic signals and a storm drain system.
The cost of the project is estimated at approximately $37 million and is scheduled to be completed in November 2014.
The project is one of the first steps in the $325 million dollar expansion of the Henry B. Gonzales Convention Center.
