According to project details shared by Harris County MUD 500 and Caldwell Companies, a new underpass will include an expanded overpass on Hwy. 290, a tunnel structure underneath the Union Pacific railroad and additional sidewalks and pedestrian crossings.

The big picture: The project has been under design and gathering funding for nearly 20 years, but according to Harris County Precinct 3 officials, funding for the project was secured in November. The Greenhouse Road connection will travel under the Union Pacific railroad crossing to the Hwy. 290 underpass with a number of factors, including:

• $81M estimated cost
• 5 agencies covering project cost
• 10-foot-wide hike and bike lanes
• 6-lane roadway

A historic 20-story downtown Houston building has officially been renamed and dedicated after the late U.S. Rep and former Houston Mayor Sylvester Turner on Dec. 17.

The gist: ​​​​​The Harris County Sylvester Turner Administration building is located at 1010 Lamar St., Houston, and houses Harris County’s Department of Economic Equity and Opportunity and will be the future site for members of the Harris County Attorney’s Office, according to county officials.

Quote of note: Members of Sylvester Turner’s family attended the ribbon-cutting ceremony alongside both the city of Houston and Harris County officials. His daughter Ashley Turner Captain said her father took a lot of pride working with the county.

“Thank you all so much for voting unanimously to honor my dad in this way by naming a building after him,” Captain said. “You know, he took a lot of pride in working closely with the county. That wasn't by accident. He really did feel like we needed to work together as the city of Houston and Harris County.”
