The new construction eliminated the need to detour traffic during times of flooding. The scope has been to increase traffic capacity from two lanes to six lanes.
The existing two-lane roadway sits at an elevation within the Trinity River floodplain and new construction will eliminate the need to detour traffic during times of flooding.
Construction begins at Morris St. in West Dallas, extends north across the two levees of the Trinity River, and connects to the Design District at Irving Blvd. The new design, performed by HNTB, will raise the elevation of Sylvan Avenue onto a 3,500 foot-long bridge, and increase traffic capacity to six lanes. It also adds pedestrian access over the Trinity River that includes bicycle lanes and six-foot wide sidewalks on each side of the bridge. The planned construction will also add an access ramp to Trammel Crow Park, a new boat ramp, and continuous streetlights, along with other aesthetic elements.

- Increasing traffic capacity from two lanes to six lanes
- Adding pedestrian access over the Trinity River that includes bicycle lanes and six-foot wide sidewalks on each side of the bridge
