One of the bridges is a pedestrian hike and bike bridge that will span US75 aka NCX or North Central Expressway, just south of the Dallas High 5 Interchange; connecting the Cottonwood Trail to the North Haven trail while the other one corrects a major point of confused drivers for decades aka the Skillman Audelia Mess. Which is at Skillman and LBJ IH-635 just east of the Dallas High 5.
The new hike and bike is the second pedestrian bridge for hike and bike that also crosses NCX US75 at Mockingbird Lane. The first one at Mockingbird is a cable stayed an cost more or less about $12 Million. It connects the Katy trail with University Crossing. All the trails get heavy use and are part of the Dallas Park and Recreation master plan in partnership with Ft Worth, bringing the total mileage about 100 miles between the two cities and around the Metroplex. The bright white steel structures are hard to miss and as is the Mockingbird cable stayed and its three mask.

Below is the new Skillman Bridge crossing LBJ IH-635 at Audelia in a straigh line alignment instead of the twist and turns and stops signs, yeild signs and a bunch of penned up frustration with drivers
