SAN ANTONIO \u2013 Construction is set to begin on San Antonio\u2019s second diverging diamond interchange<\/a>, according to the Texas Department of Transportation, planned for the Southeast Side.<\/p>\n

The $40 million infrastructure project aims to reduce congestion on Interstate 37 near Southeast Military Drive and make the corridor safer. It is expected to be complete in 2029.<\/p>\n

A diverging diamond interchange shifts traffic to the opposite side of a roadway while moving through an intersection, so that left turns can be made without waiting for oncoming traffic to stop.<\/p>\n

Traffic experts say the design significantly reduces the number of possible points where a crash can occur, while moving higher volumes of traffic more efficiently.<\/p>\n

\"\"State traffic models project up to a 90% reduction in travel time when exiting Interstate 37 onto Southeast Military Drive. (Texas Department of Transportation)<\/p>\n

State traffic models project a 90% reduction in travel times for those exiting southbound I-37 onto Southeast Military Street.<\/p>\n

While construction will require temporary lane closures, state transportation officials said most closures will occur overnight between 9 p.m. and 5 a.m. on weekdays to minimize disruptions. TxDOT said daytime and weekend work may also occur to keep the project on schedule.<\/p>\n
