*No public benefits were identified since the streets do not currently
cross the railroad.
SH 105
State Highway (SH) 105 is a two-lane roadway in Liberty County that would cross the potential
new Dayton to Cleveland rail corridor near Cleveland, Texas. Approximately
12,200 daily vehicles currently use this roadway. The identified two-lane
roadway overpass would separate vehicular traffic from the potential
Dayton-Cleveland rail line.
Access to adjacent properties will be maintained via access roads alongside
the main roadway along with an at-grade u-turn located beneath the overpass on
the west side of the railroad.
The grade separation of SH 105 is estimated to cost $6,000,000. The estimated
public benefit could not be calculated for the grade separation of SH 105 since
the roadway currently does not cross the railroad.

FM 1960
Farm-to-Market (FM) 1960 is a two-lane roadway in Liberty County that would cross the
potential new Dayton to Cleveland rail corridor near Dayton, Texas.
Approximately 10,900 daily vehicles currently use this roadway. The identified
two-lane roadway overpass would separate vehicular traffic from the potential
Dayton-Cleveland rail line.
Access to adjacent properties will be maintained via access roads alongside
the main roadway along with at-grade u-turns located beneath the overpass on
each side of the railroad.
The grade separation of FM 1960 is estimated to cost $6,800,000. The
estimated public benefit could not be calculated for the grade separation of FM
1960 since the roadway currently does not cross the railroad.

FM 787
Farm-to-Market (FM) 787 is a two-lane roadway in Liberty County that would cross the potential
new Dayton to Cleveland rail corridor near Cleveland, Texas. Approximately 9,900
daily vehicles currently use this roadway. The identified two-lane roadway
overpass would separate vehicular traffic from the potential Dayton-Cleveland
rail mainline as well as the wye connections to the Lufkin Subdivision. No
properties currently access FM 787 at the location of the grade separation, and
are therefore not affected by the overpass.
The grade separation of FM 787 is estimated to cost $5,600,000. The estimated
public benefit could not be calculated for the grade separation of FM 787
because the roadway currently does not cross the railroad.

US 90A
US 90A is a four-lane median separated roadway in Liberty County that would
cross the potential new Dayton to Cleveland rail corridor near Dayton, Texas.
Approximately 13,800 daily vehicles currently use this roadway. In order to
separate vehicular traffic from the potential Dayton-Cleveland rail line, the US
90A roadway would overpass the new wye connections between the New Subdivision
and the existing Lafayette Subdivision. The New Subdivision mainline also would
overpass the US 90A mainlines as well as the existing Lafayette Subdivision
mainline. In summary, grade separating vehicular traffic from rail traffic on
the new subdivision would require three separate overpass structures.
The grade separation of US 90A over the new wye connections between the new
subdivision rail line and the existing Lafayette Subdivision is estimated to
cost $18,000,000, and the grade separation of the new subdivision over the US
90A mainlanes is estimated to cost $19,000,000, for a total cost of $37,000,000.
Under existing conditions, the Baytown Subdivision mainline crosses US 90A
at-grade, and connects and terminates at the Lafayette Subdivision at Dayton
Junction in the city of Dayton. The at-grade crossing is in close proximity to
the intersection of SH 146 and US 90A. The Baytown Subdivision has a very sharp
curve just before the at-grade crossing requiring the train speed to be reduced
to 10 mph, which results in closing US 90A for 20 minutes or longer when a train
is passing. There are approximately eleven trains per day crossing US 90A.
The TxDOT Beaumont District has created preliminary and conceptual plans that
relocate and grade separate the existing crossing west of Dayton. The identified
location is approximately in the same location where the new subdivision crosses
US 90A and the Lafayette Subdivision. Proper coordination between the conceptual
layout of the US 90A/new subdivision crossing included in this study and the
conceptual plans created by the TxDOT Beaumont District is imperative prior to
final design of the grade separation of US 90A.
