The Impact of an Elevated Metrorail
through Tysons

Construction Phase

• Increased road network congestion and
  shutdowns from
  • above grade construction
  • Rt. 7 reconfiguration
  • utility relocations throughout Tysons
  • concurrent HOT Lane construction and improvements to Route 29
• Increased business disruption and retail
  community impacts
• Reduced tax revenue resulting from
  business disruption
• Increased construction impacts — noise, air pollution (congestion), and dust
• Increased construction risk (potential cost) resulting from
  • extensive utility relocations
  • reworking of roadways
  • weather

Post-Construction Phase

• Ugly, massive elevated structure
  • 3 miles long
  • 35 feet high (65 feet max.)
  • columns every 70 feet (typical)
  • 1,800 foot wall along Rt. 7 (up to 40 feet high)
• Train noise pollution
• Driving hazard / reduced visibility around columns
• Reduced light, air, and open space
• Possible for social divide
• Potential for public nuisance around structure — graffiti, trash, degraded environment, track run-off, etc.

The Impact of a Tunnel for Metrorail
under Tysons

Construction Phase

• Dramatically reduced road network and utility impacts
• Minimized business disruption and retail community impact
• Minimized tax revenue loss resulting from business disruption
• Dramatically reduced construction impact
• Minimized construction risk (cost control)

Post-Construction Phase

• Minimized visual impact, visible only at station entrances
• No train noise pollution
• Improved walking environment
• More room for parks and community space
• No potential for social divide
• Minimized potentials for public nuisance
• Improved opportunities for local business around stations
• Higher commercial tax revenue to support
  schools and other services
• Increased connectivity across major thoroughfares
• More user friendly
• Reduced operating cost (higher return on public investment)
• Doubled lifespan (reduced lifecycle cost—
  long-term savings)
• Higher ridership potential
