IH-10 inside the loop: Frontage lanes and flood mitigation ponds

Why this matters

The history

The 5.8-mile segment of IH-10 from the IH-610 west loop east to IH-45 was constructed in the 1960s and opened in December 1968. The 10-lane freeway project claimed acres of land and displaced homes in neighboring communities where people went to school, lived, worked and shopped. Commercial properties developed along the freeway feeders in some places, and in other places, residential use prevailed. Homeowners blocks away from the project ultimately felt the freeway's impact as rental properties and industrial businesses replaced many of the homesteads in the neighborhoods. The railroad trestle west of TC Jester built when the freeway was constructed, made history due its expanse and massive grape arbor style superstructure.

IH-10 neighborhoods inside the loop
Inside the loop, IH-10 is bordered by Memorial Park (Houston's largest and most-visited city park), Cottage Grove Park, White Oak Bayou, White Oak Park, and some of Houston's most historic residential neighborhoods.

State of the art design: Depressed area impressive

This section of IH-10 was unique in another significant way: the one-and-a-half-mile section that passes through the Cottage Grove neighborhood was constructed below grade. Surveys taken in 1971 reported favorable press from neighboring communities. The design engineer for the project, Bill Ward, described the depressed section as "a superior design, making it easier for cars exiting off the freeway to decelerate and cars entering the freeway to accelerate. Furthermore noise from traffic on the depressed section is less disturbing on abutting property owners." Since IH-10's construction, other Houston neighborhoods have benefited from the below-grade designs of US-59 (Southwest Freeway) inside the loop, and IH-45 (North Freeway) north of downtown.

IH-10 is below grade
The current depressed design of IH-10 helps protect Cottage Grove, Woodcrest, and other neighborhoods from the flooding, noise, air quality, and visual impacts of increasing freeway traffic. These sound-absorbing earthen embankments and trees may be eliminated to accommodate proposed elevated frontage lanes.

Plans for the corridor

TXDOT has presented preliminary plans for two projects related to IH-10 expansion inside the IH-610 loop. They include plans to:

McDonald to Cohn including Cottage Grove Park

Reinerman to Shepherd

Elevation


Proposed lanes will be approximately 30’ above grade. No sound mitigation is included in plan yet. Sufficient ROW exists for proposed frontage lanes to be below grade instead.


Schematic


Proposed relocation of pedestrian bridge puts southern terminus abutting UPRR ROW. Sidewalk access may be an issue.


Eastbound entry ramp from TC Jester eliminated (extends emergency vehicle access to IH10 approx. 1600' east through 2 signalized intersections). Sound-absorbing earthen embankment replaced with concrete retaining wall (must model noise impacts).

Challenges

Many residents from Cottage Grove and Woodcrest want both IH-10 main lanes and any frontage lanes to remain below grade. They want any expansion to stay within the existing right-of-way. They are concerned about the impact of redirected freeway access for industrial and emergency vehicles, and the traffic and development impacts of new continuous frontage lanes on the urban community environment. Union Pacific Railroad wants its route to remain operable during any roadway construction.

Cottage Grove Park may be shadowed by proposed frontage lanes
Proposed elevated frontage lanes would introduce overhead traffic at the fence line near the basketball court and baseball field of Cottage Grove Park. At 23' above the existing at-grade railroad trestle, the proposed frontage lanes would be significantly taller than the basketball canopy shown. This photo shows the current view of the freeway. Because the main lanes are below grade, IH-10 is not visible from local streets or homes built on the north or south sides of the freeway.
