What’s next?
As of March, construction crews were focused on continuing work on the southern portion of Phase 1 of the project. Work on Phase 2 will start in late 2024 at White Oak Bayou, and crews will work north toward 15th Street. Depending on the location and space, the paving will be done in two or three steps, Weesner said. More details will be known after the authority hires a contractor, she said. Meanwhile, officials with the Houston Public Works Department said the city’s reviews of road narrowing and bike lane projects are ongoing. Construction on the remaining phases of Shepherd and Durham will take place according to the following timeline: • Construction on Phase 2 will begin in late 2024. • Construction on Phase 1 will be finished in fall 2025. • Construction on Phase 2 will be finished in late 2027.
