Ravenswood Avenue Alternate 1 Underpass Grade Separation Advantages: No raised embankment required Possibly less disruptive to community during construction Disadvantages: Greater impact on surrounding properties 3
Ravenswood Avenue Alternate 2 Split Grade Separation Advantages: Reduced impact on surrounding property Better vehicle circulation Better station layout Disadvantages: Raised embankment Possible more disruption during construction 4
5 Ravenswood Avenue
Alternate 1 Underpass Grade Separation Advantages: No track embankment required Disadvantages: 20 Deep narrow underpass required Oak Grove Avenue Access to property near tracks disrupted Could require modification of existing land use 6
Oak Grove Avenue Alternate 2 Split Grade Separation Advantages: Minimizes impact on existing land use Traffic patterns can be maintained Disadvantages: Requires raised track embankment Disruptions during construction 7
