Collingsworth Street
Collingsworth Street is currently a four-lane roadway that is a major east-west
arterial inside Loop 610 and crosses the railroad at-grade in Harris County on
the north side of Houston. Approximately 6,000 vehicles cross the UPRR at this
location daily. The identified four-lane roadway overpass would separate
vehicular traffic from the UPRR West Belt Subdivision.
The existing double tracks are currently under design to become a triple
track configuration as part of the Hardy Toll Road Extension improvement. The
City of Houston, in cooperation with the Harris County Toll Road Authority, has
consultants currently under contract to design the grade separation of Collingsworth Street.
Environmental Constraints
The environmental constraints located in the vicinity of Collingsworth Street
consist of adjacent industrial properties, a pipeline that runs perpendicular to
the proposed overpass, a fire station and nearby churches. Right-of-way
acquisition of the adjacent properties accounts for approximately 59 percent of
the estimated cost to implement this grade separation.
Cost
The grade separation of Collingsworth Street is estimated to cost $9,000,000.
The estimated public benefit calculated for the grade separation of Collingsworth Street is $2,900,000, which is approximately 32 percent of the
estimated cost of construction.

Leeland Street
Leeland Street is currently a four-lane roadway that crosses the railroad
at-grade in Harris County in downtown Houston. Approximately 6,000 vehicles
cross the UPRR at this location daily. According to collision data received from
the H-GAC Traffic Safety Program and the FRA, four crashes occurred at the
Leeland Street crossing between 1990 and 2003.
The identified four-lane roadway underpass would separate vehicular traffic
from the UPRR West Belt Subdivision. It would also result in the closure of
Cullen Blvd due to significant grade differentials (vertical clearance
requirements) with the Leeland underpass.
Access to adjacent properties will be achieved through the use of the current
roadway network in the vicinity. Access to Leeland Street along the potential
underpass ramps will be eliminated; however access to adjacent roadways is
available for all affected properties. Traffic along Cullen Boulevard, which
would be closed, may be rerouted to adjacent roadways as well.
Environmental Constraints
The environmental constraints located in the vicinity of Leeland Street
consist of adjacent commercial, residential, and industrial properties.
Right-of-way acquisition of the adjacent properties accounts for approximately
five percent of the estimated cost to implement this grade separation.
Cost
The grade separation of Leeland Street is estimated to cost $7,000,000. The
estimated public benefit calculated for the grade separation of Leeland Street
is $3,900,000, which is approximately 50 percent of the estimated cost of
construction.

Lyons Avenue
Lyons Avenue is currently a two-lane roadway that crosses the railroad at-grade
in Harris County in downtown Houston. Approximately 4,600 vehicles cross the
UPRR at this location daily. The identified two-lane roadway underpass would
separate vehicular traffic from the UPRR West Belt Subdivision.
Access to adjacent properties will be achieved through the use of the current
roadway network. Access to Lyons Avenue along the potential underpass ramps will
be eliminated; however access to adjacent roadways such as Semmes, West, McCall,
and Jensen Streets, is available for all affected properties except for the
property directly northeast of the crossing.
Environmental Constraints
The environmental constraints located in the vicinity of Lyons Avenue consist
of adjacent commercial, residential, and industrial properties as well as
transmission lines. Right-of-way acquisition of the adjacent properties accounts
for approximately four percent of the estimated cost to implement this grade
separation.
Cost
The grade separation of Lyons Avenue is estimated to cost $6,000,000. The
estimated public benefit calculated for the grade separation of Lyons Avenue is
$130,000, which is approximately two percent of the estimated cost of
construction.

Navigation Boulevard/Commerce Street
Navigation Boulevard is currently a four-lane roadway that, at the railroad
crossing, underpasses the West Belt Subdivision. The roadway is located
immediately east of downtown and US 59. However, this crossing has low vertical
clearance and narrows at the underpass crossing with the railroad.
Commerce Street crosses the railroad at-grade above the existing Navigation
Boulevard underpass. The existing underpass is identified to be improved in
order to increase vertical clearance and widened to accommodate additional
traffic volumes as well grade separate Commerce Street from the railroad.
According to collision data received from the H-GAC and the FRA, two crashes
occurred at the Commerce Street crossing between 1990 and 2003.
Environmental Constraints
The constraints located near the underpass consist of adjacent industrial
properties, a school, a fire station, and nearby churches. Right-of-way
acquisition of the adjacent properties accounts for approximately three percent
of the estimated cost to implement this improvement.
Cost
The grade separation of Navigation Boulevard is estimated to cost
$25,000,000. The estimated public benefit calculated for the grade separation of Navigation Boulevard and Commerce Street is $13,000,000, which is 52 percent of
the estimated cost of construction.
Back to top
Quitman Street
Quitman Street is currently a two-lane east-west arterial roadway that crosses
the railroad at-grade in Harris County located inside Loop 610 in north Houston.
Approximately 8,000 vehicles cross the UPRR at this location daily. The
identified four-lane roadway overpass would separate vehicular traffic from the
UPRR West Belt Subdivision.
The existing double tracks of the West Belt Subdivision are currently under
design to become a triple track configuration as part of the Hardy Toll Road
Extension improvement. The Harris County Toll Road Authority has engineering
consultants currently under contract to design this four-lane grade separation.
Environmental Constraints
The constraints located near Quitman Street consist of adjacent commercial,
residential, and industrial properties as well as nearby schools and churches.
Right-of-way acquisition of adjacent properties accounts for approximately 27
percent of the cost to implement this grade separation.
Cost
The grade separation of Quitman Street is estimated to cost $7,400,000. The
estimated public benefit calculated for the grade separation of Quitman Street
is $20,000,000, which is over 2 times greater than the estimated cost of
construction.
Back to top
Scott Street and York Street
Scott Street and York Street are two-lane roadways that operate as one-way pairs
and cross the railroad at-grade in Harris County, east of downtown Houston. A
combined average of 27,500 vehicles cross the railroad at these locations daily.
These one way pairs are identified to be combined into a single overpass over
the railroad, which would separate vehicular traffic from the UPRR West Belt
Subdivision.
Access for adjacent properties west of Scott Street would be maintained via
the existing roadways west of Scott Street. York Street is identified to be
closed on the UPRR West Belt Subdivision and UPRR Galveston Subdivision.
Environmental Constraints
The environmental constraints located in the vicinity of Scott Street and
York Street consist of adjacent residential, commercial, and industrial
properties. Right-of-way acquisition of the adjacent properties accounts for
approximately 19 percent of the estimated cost to implement this grade
separation.
Cost
The grade separation of Scott Street and York Street is estimated to cost
$11,000,000. The estimated public benefit calculated for the grade separation of Scott Street and York Street is $18,000,000, which is over 60 percent greater
than the estimated cost of construction.
