  • 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.

Concept #1: Viaduct at 148th Street (Alternate 1)

  • Estimated construction cost: $ 8.2 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

Disadvantages

  • Impacts to Millard Lumber employee parking
  • Impacts to agricultural property
  • Lengthy access/frontage roads required

Concept #2: Viaduct at 148th 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 148th Street (Alternate 3A)

  • Estimated construction cost: $7.7 Million
  • Grade-separated pedestrian crossing at 141st 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 148th Street is maintained as the primary

alignment including connection to Highway 6

  • Continuity to existing road network

Disadvantages

  • Impacts to future development west of 148th Street
  • Impacts to agricultural property

Concept #3B: Viaduct at 148th Street (Alternate 3B)

  • Estimated construction cost: $10.0 Million
  • Grade-separated pedestrian crossing at 141st 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 148th 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 141st 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 162nd Street (Eliminated)

  • Estimated construction cost: $5.0 Million
  • Grade-separated pedestrian crossing at 141st 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 141st 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 141st 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
