• New two‐track bridge upstream of existing bridge
• Retain existing bridge
• New two‐track bridge upstream of existing bridge
• Replace existing bridge

Steel Deck Plate Girder Steel Through Plate Girder
• Both options feasible under either Action Alternative• Structure type to be determined in final design

Conceptual EngineeringNew GWMP Railroad Bridge• Existing through girder bridge with arched steel and stone masonry• Center pier located in median• New bridge(s) would be through plate girder with similar aesthetics• Bridges over NPS property would be designed compatible with
existing resources

Bike‐Pedestrian CrossingPotential 4(f) Mitigation
Option 1: Shared RR Bridge Substructure• Prefabricated truss
superstructures• Extended railroad piers• Larger permanent footprint• Would require substantial
security measures including railing or screening between bridges
• More difficult inspection and maintenance procedures
• More expensive than Option 2
10
Option 2: Independent Bridge• Prefabricated truss
superstructures• Single column piers • Smaller permanent footprint• 25‐foot separation from railroad
bridge• Simpler inspection and
maintenance• Preferred by railroad operators
and NPS • Construction cost
approximately 20% less than Option 1

Identification of Historic PropertiesPhase IA Archaeological Assessment
Phase IA Process• Coordinated with DC and VA SHPO
• Documented history of LOD
• Site visit to verify desktop analysis
• Identified areas as having high, low, or no potential for resources

Actio
n Alternative A
Physical Effects: Construction of a new railroad bridge would remove contributing vegetation. DIRECT ADVERSE EFFECT.
Visual Effects: Despite visible changes along Ohio Drive SW and along perimeter of park, they do not rise to the level of adverse. NO ADVERSE EFFECT.
Noise and Vibration Effects: No exceedances of FTA thresholds at test locations. NO ADVERSE EFFECT.
Actio
n Alternative B Physical Effects: Removal of contributing Long Bridge represents
a total loss of contributing feature. Construction of a new railroad bridge would remove contributing vegetation. DIRECT ADVERSE EFFECT.
Visual Effects: Same as Action Alternative A.

mulative
Construction of a bike‐pedestrian crossing and access ramp would remove contributing vegetation. DIRECT ADVERSE EFFECT.
Tempo
rary
Construction staging and access would diminish integrity of feeling, association, and setting of the HD. Temporary construction noise has potential to diminish integrity of contributing U.S. Engineers’ Storehouse. DIRECT AND INDIRECT ADVERSE EFFECT.
