o Alternate C - realignment moving intersection W, +/-‘s & cost
o Alternate D - existing geometry, signal, +/-‘s & cost
Ø Alternate Impact Matrix-recommendation
Ø Additional considerations

o County bridges on Barlow and Terex
o Pedestrian/bike connection across intersection
Barlow Road Discussion
Ø Existing conditions -accidents, speeds, geometry, pavement condition, intersection inclusion
Ø Proposed Alternatives
o Alternate 1 - 11’ lanes with ½ ft. paved berms, no geometry improvements, +/-‘s & cost
o Alternate 2 - 11’ lanes with 1 ½ ft. paved berms, geometry improvements, +/-‘s & cost
o Alternate 3 - 12’ lanes with 1 ½ ft. paved berms, geometry improvements, +/-‘s & cost
o Alternate 4 - 12’ lanes + 1 ft. offset with curb, geometry improvements, +/-‘s & cost
Ø Alternative Summary - Recommendation
Ø Additional Considerations:
o Status of borrow site for RR fill
o Maintenance of traffic
o Coordination with RR owner
o Path and Walk width, type of material, limits
o Drainage/Swales
o Schedule
o Right of way impacts
o Tree impacts
o Traffic calming features
o Bike use - sharrows
