Conceptual Engineering

New 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 Crossing

Potential 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 Properties

Phase 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

Archaeology Next Steps

Short term

  • Phase IA submitted to SHPOs
  • Draft EIS identifies Preferred

Alternative

Long term

  • Prepare final design for Preferred

Alternative

  • Continue Section 106 consultation
  • Conduct recommended

investigations based on assessment and SHPO consultation prior to construction

Construction of a bike‐pedestrian crossing and access ramp would remove contributing vegetation. DIRECT ADVERSE EFFECT.

Temporary

Construction staging, access, and trail relocation would diminish integrity of feeling, association, and setting of the GWMP. DIRECT AND INDIRECT ADVERSE EFFECT.

Assessment of Effects

East and West Potomac Parks (DC)

36 Action 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.

Action 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. Noise and Vibration Effects: Same as Action Alternative A.

Cumulative

Construction of a bike‐pedestrian crossing and access ramp would remove contributing vegetation. DIRECT ADVERSE EFFECT.

Temporary

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.

Resolution of Effects

  • Adverse effects identified for

the National Mall, GWMP, MVMH, and East and West Potomac Parks historic districts.

  • Adverse effects would be

intensified in Action Alternative B

  • Adverse effects will be resolved

through appropriate avoidance, minimization, and mitigation measures and documented in a MOA or PA

47

slide-48
SLIDE 48

Resolution of Effects

Some measures already identified through consultation:

48

  • Retain Long Bridge and GWMP railroad bridge

(Action Alternative A)

  • Dismissed alternatives outside of Long Bridge Corridor (did not

meet Purpose and Need)

  • New bridge(s) to be compatible with existing bridges
  • Compatible aesthetic treatment of new bridges within NPS

properties

  • Appropriate construction management and screening

Mitigation

  • New trees and other vegetation to replace mature vegetation

and screen new structures

Minimization Avoidance

FRA and DDOT welcome additional ideas on potential avoidance, minimization, and mitigation options from SHPOs and Consulting Parties
