The TxDOT Houston District is proposing design changes on State Highway (SH) 146 from Spencer Highway to Red Bluff Road in Harris County, Texas. The proposed changes are expected to improve mobility and congestion, accommodate pedestrians and bicyclists, and facilitate hurricane evacuation.

Currently, SH 146 is a four-lane divided freeway from Spencer Highway to Red Bluff Road. There are existing north and southbound frontage roads between Spencer Highway and McCabe Road. The access is limited from Port Road and Red Bluff Road to the existing southbound frontage road. SH 146 (Red Bluff Road to Spencer Highway) is part of a multi-segment improvement plan along SH 146, which started as a Major Investment Study conducted in the late 1990s. SH 146 serves as a major roadway connecting Houston to Galveston.

Proposed Improvements

The proposed improvements to SH 146 include:

From Spencer Highway to Fairmont Parkway

• Adding one lane in each direction
• Reconstructing the bridge over Little Cedar Bayou
• Adding sidewalks along the frontage roads from Spencer Highway to McCabe Road
• Reconstructing the roadways to connect into the mainlanes

From Fairmont Parkway to Red Bluff Road

• Adding one lane in each direction
• Reconstructing the mainlanes to tie into two existing ramps and direct connectors before Port Road
• Reconstructing the roadways to connect into the mainlanes
• Adding two frontage roads in each direction from McCabe Road to Shore Acres Boulevard 
• Adding two northbound frontage roads from Port Road to Red Bluff Road
• Adding three southbound frontage roads from Port Road to Red Bluff Road
• Reconstructing the bridges over West Fairmont Parkway and Taylor Lake
• Adding an additional lane in each direction to bridges over Wharton Weems Boulevard, Lakes at Fairmont Greens Subdivision, Shore Acres Boulevard, and Red Bluff Road
• Restriping the bridge from two lanes to three lanes in each direction at Port Road
• Add sidewalks in each direction along portions of frontage roads from Port Road to Red Bluff Road 
• Adding sidepaths in each direction along frontage roads from McCabe Road and Shore Acres Boulevard

The proposed design changes are not anticipated to require any additional right of way.
