• Conduct Grade Separation Study • A minimum exposure factor of 50,000 for a single crossing shall be required for identification as a potential location. (Exposure factor = # trains/day x # cars/day) • A new grade separation project will require closing a minimum of two public at-grade crossings.

• Ability to eliminate crossing hazard and improve safety • Cost • Connectivity to existing/future roadway network • Impact to private property, including access • Public support • Ability to accommodate truck and farm machinery traffic • Environmental impacts • Utility impacts • Benefits (how much traffic is served)
N. 141st St. Jamestown St. Heywood St. N. 162nd St.
Concept #1: Viaduct at 148 th Street (Alternate 1) • Estimated construction cost: $ 8.2 Million • Grade-separated pedestrian crossing at 141 st Street: $2.3 Million • Projected traffic: 4,400 vehicles per day Reasons for Consideration • Relative close proximity to downtown • Reduces area required for right-of-way acquisition • Accommodates largest volume of traffic, including truck traffic • Sidewalk/trail along this alignment would best accommodate future residential development and present school locations • Continuity to existing road network Disadvantages • Impacts to Millard Lumber employee parking • Impacts to agricultural property • Lengthy access/frontage roads required
Concept #2: Viaduct at 148 th Street (Alternate 2) • Estimated construction cost: $8.4 Million • Grade-separated pedestrian crossing at 141st Street: $2.3 Million • Projected traffic: 4,400 vehicles per day Reasons for Consideration • Relative close proximity to downtown • Reduces area required for right-of-way acquisition • Accommodates largest volume of traffic, including truck traffic • Sidewalk/trail along this alignment would best accommodate future residential development and present school locations • Continuity to existing road network • More direct connection to US-6 Disadvantages • Impacts to future development west of 148th Street • Impacts to agricultural property • Impacts to commercial property
Concept #3A: Viaduct at 148 th Street (Alternate 3A) • Estimated construction cost: $7.7 Million • Grade-separated pedestrian crossing at 141 st Street: $2.3 Million • Projected traffic: 4,300 vehicles per day Reasons for Consideration • Relative close proximity to downtown • Reduces area required for right-of-way acquisition • Accommodates largest volume of traffic, including truck traffic • Sidewalk/trail along this alignment would best accommodate future residential development and present school locations • Existing 148 th Street is maintained as the primary alignment including connection to Highway 6 • Continuity to existing road network Disadvantages • Impacts to future development west of 148 th Street • Impacts to agricultural property
Concept #3B: Viaduct at 148 th Street (Alternate 3B) • Estimated construction cost: $10.0 Million • Grade-separated pedestrian crossing at 141 st Street: $2.3 Million • Projected traffic: 4,300 vehicles per day Reasons for Consideration • Relative close proximity to downtown • Access to downtown • Reduces area required for right-of-way acquisition • Accommodates largest volume of traffic, including truck traffic • Sidewalk/trail along this alignment would best accommodate future residential development and present school locations • Existing 148 th Street is maintained as the primary alignment including connection to Highway 6 • Continuity to existing road network Disadvantages • Impacts to future commercial development • Impacts to commercial property • Impacts to agricultural property
Concept #4: Viaduct at 152nd Street (Eliminated) • Estimated construction cost: $7.4 Million • Grade-separated pedestrian crossing at 141 st Street: $2.3 Million • Projected traffic: 2,900 vehicles per day Reasons for Elimination • Distance from central Waverly: • Increased vehicle travel distance/times • Too remote to provide pedestrian access across BNSF Railway and U.S. Highway 6 • Increased emergency response times • Lower traffic utilization • No direct access to downtown • Property impacts Reasons for Initial Consideration • Provided an alternate viaduct location to 148th Street • Viaduct constructed near eastern edge of future land use plan
Concept #5: Viaduct at 162 nd Street (Eliminated) • Estimated construction cost: $5.0 Million • Grade-separated pedestrian crossing at 141 st Street: $2.3 Million • Projected traffic: 300 vehicles per day Reasons for Elimination • Distance from central Waverly: • Increased vehicle travel distance/times • Too remote to provide pedestrian access across BNSF Railway and U.S. Highway 6 • Increased emergency response times • Lowest traffic utilization • No direct access to downtown Reasons for Initial Consideration • Lower construction cost • Fewer property impacts • Better accommodate future growth in far eastern reaches of future city limits
Concept #6: Viaduct at 141 st Street (Eliminated) • Estimated construction cost: $7.0 Million • Grade-separated pedestrian crossing at 148th Street: $2.3 Million • Projected traffic: 5,800 vehicles per day Reasons for Elimination • Property impacts: • Home relocations • Residential and commercial driveway and access closures/reconfiguration • Retaining wall in close proximity to homes • Intersecting street closures necessary • Increased traffic volumes on residential streets • Difficult turning movements for viaduct truck traffic • Does not accommodate farm machinery Reasons for Initial Consideration • Provides direct access to north and south of U.S. Highway 6 near center of Waverly • Along same alignment as existing 141st Street
Concept #7: Underpass at 141 st Street (Eliminated) • Estimated construction cost: Not Calculated For This Concept • Grade-separated pedestrian crossing at 148th Street: $2.3 M • Projected traffic: 5,800 vehicles per day Reasons for Elimination • Property impacts: • Residential and commercial driveway and access closures/reconfiguration • Retaining wall in close proximity to homes • Increased traffic volumes on residential streets • Difficult turning movements for viaduct truck traffic • Does not meet Nebraska Minimum Design Standards- steep grades • Does not accommodate farm machinery • Long term maintenance and operational costs Reasons for Initial Consideration • Provides direct access to north and south of U.S. Highway 6 near center of Waverly • Along same alignment as existing 141st Street
