FM 2978
FM 2978 is currently a two-lane roadway that crosses the railroad at-grade in
Harris County near the city of Tomball. Approximately 16,600 vehicles cross the
railroad at this location daily. The identified two-lane roadway overpass would
separate vehicular traffic from the UPRR Navasota Subdivision. According to
collision data received from the H-GAC Traffic Safety Program and the FRA, one
crash occurred at the FM 2978 crossing between 1990 and 2003.
Access to adjacent properties will be maintained via existing access roads
alongside the main roadway along with at-grade u-turns located beneath the
overpass on each side of the railroad.
The environmental constraints located in the vicinity of FM 2978 consist of a
pipeline and adjacent properties. Right-of-way acquisition of the adjacent
properties would not contribute to the estimated cost to implement this grade
separation since the grade separation may be constructed within the existing
right-of-way.
The grade separation of FM 2978 is estimated to cost $11,000,000. The
estimated public benefit calculated for the grade separation of FM 2978 is
$6,100,000, which is 55 percent of the estimated cost of construction.

Kuykendahl Road
Kuykendahl Road is currently a two-lane roadway that crosses the railroad
at-grade in Harris County near The Woodlands. Approximately 18,800 vehicles
cross the railroad at this location daily. The identified four-lane roadway
overpass would separate vehicular traffic from the UPRR Navasota Subdivision.
Kuykendahl Road splits into Kuykendahl-Hufsmith Road, creating a three-way grade
separated interchange.
The purpose of the planned expansion of Kuykendahl Road from a two-lane to a
four-lane roadway is to accommodate the additional future traffic that will be
associated with large planned developments of The Woodlands north of the
Kuykendahl intersection. Access to adjacent properties will be maintained via
at-grade access roads alongside the main roadway.
The environmental constraints located in the vicinity of Kuykendahl Road
consist of adjacent residential and commercial properties. Right-of-way
acquisition of the adjacent properties accounts for approximately 23 percent of
the estimated cost to implement this grade separation.
The grade separation of Kuykendahl Road is estimated to cost $18,000,000. The
estimated public benefit calculated for the grade separation of Kuykendahl Road
is $6,400,000, which is 36 percent of the estimated cost of construction.

Steubner Airline Road
Steubner-Airline Road is currently a two-lane roadway that crosses the
railroad at-grade in Harris County near the city of Tomball. Approximately 1,900
vehicles cross the UPRR at this location daily. The identified two-lane roadway
overpass would separate vehicular traffic from the UPRR Navasota Subdivision.
Access to adjacent properties will be maintained along Kuykendahl-Hufsmith Road,
which runs parallel to the Navasota Subdivision. An access roadway is identified
to be constructed in order to provide connectivity between Kuykendahl-Hufsmith
Road and Steubner-Airline Road.
The environmental constraints located in the vicinity of Steubner-Airline
Road consist of adjacent residential properties. Right-of-way acquisition of the
adjacent properties accounts for less than 1 percent of the estimated cost to
implement this grade separation.
The grade separation of Steubner-Airline Road is estimated to cost
$5,100,000. The estimated public benefit calculated for the grade separation of
Steubner-Airline Road is $200,000, which is approximately four percent of the
estimated cost of construction.
