Review purpose and needs for the project Identify alternatives (solutions) to address the
needs Discuss next steps
2
3
Regional and local traffic Approximately 3,700 vehicles per day 16% trucks
Constructed in 1998 Existing asphalt 8 inches thick asphalt 24 crashes in 5 year period Run-off-the-road crashes present Ice and snow primary factors
4
Purpose Maximize the life of the pavement Improve safety
Needs Deteriorating pavement (cracking and rutting) Four culvert pipes in poor condition Deteriorating railroad crossing pavement
5
6
7
8
Four culverts are in poor condition Proposing to replace three Two by railroad in Oxford One by 5th Drive Repair one 1 mile east of 5th Drive
Size/location unchanged
9
10
Resurface Recycle Replacement
All alternatives include: Culvert pipe repair Railroad crossing surface replacement Five-day detour required (WIS 13, WIS 21 and I-39) Centerline rumble strips Safety edge installation
11
12
Reduce head-on fatal/injury crashes by 44% Increase “awareness” Inattentive driving Limited Visibility Rain, snow or fog
Low installation cost
Not installed near intersections or commercial driveways
13
6% reduction in all crashes Low cost of installation Reduces hazard of low shoulders Creates “smooth transition” back onto roadway
14
Normal Edge Safety Edge
15
Resurface Mill (remove) 2 inches of pavement Place 1.75 inches of new pavement
Temporarily eliminates rutting/cracking. Underlying issues not addressed.
Limited traffic impacts (flagging operation, 5 day detour)
Cost = $1.5 million – $2 million
16
Remove 2 inches of asphaltPlace 1.75 inches of asphaltInstall centerline rumble stripsLane and shoulder width unchanged
17
Recycle Mill (remove) 2 inches of asphalt Cold-in-place recycle 4 inches of asphalt Place 1.75 inches of new asphalt
Addresses more of the rutting and cracking issues Limited traffic impacts (flagging operation, five-day
detour) Cost = $2.4 million – $3 million
18
Remove 2 inches of asphaltRecycle 4 inches of asphaltPlace 1.75 inches of asphaltInstall centerline rumble stripsLane and shoulder width unchanged
19
Replacement Remove all pavement Replace with new pavement
Removes pavement not past its useful life (wastes money) Possible real estate impacts (slope widening) Greater traffic impact (four-month detour) Cost = $3.7 million – $4.5 million
20
Remove all existing asphaltReplace with 6 inches of new asphaltInstall centerline rumble stripsLane and shoulder width unchangedSlopes possibly widened
21
Five-day detour (Monday – Friday) State signed detour route via WIS 13, WIS 21, I-39 Local access maintained at all times
