The southbound I-35 exit ramp to Airport Boulevard is closed temporarily until 9 p.m. on Oct. 30, weather permitting, according to a news release from the Texas Department of Transportation. The exit closed on Oct. 15. Drivers on I-35 who wish to exit to Airport Boulevard are advised to use the 51st Street exit and travel through the 51st Street intersection. The southbound I-35 entrance ramp south of 51st Street will close the evening of Thursday, Oct. 26. Crews will construct a new entrance and exit ramp to Airport Boulevard. As part of the same project, a new southbound intersection bypass lane will be added to the exit to allow through-traffic to bypass the traffic signal; the southbound frontage lane will be realigned to add a new roundabout to improve flow and safety; and bicycle and pedestrian lanes will be enhanced. The $16.5 million project was awarded to contractor Capital Excavation Company and is expected to be complete in spring 2018.
