Background Info:
• Segment of Route I-295 constructed between 1972 & 1974
• Has reached terminal serviceability – 36 Years
• Deteriorating Pavement due to Alkali Silica Reaction (ASR)
• Rough Ride
Major Proposed Improvements:
• Rubblize concrete pavement. 8” bituminous overlay.
• Reconstruct bituminous shoulders (1′ widening)
• Improve vertical clearance under 3 bridges
• Add ITS facilities.
• Update Guide Rail, Clear Zone, Acceleration Lanes.
Traffic Staging and Construction:
• Lane Closure Alternatives – Continuous,
Weekend, Night-time
• User Delay – Duration, Daily Impact, Cost
• Constructibility – Quality, Safety, Cost
• Public Outreach – Internet, On-Site, Community

Traffic Staging Highlights:
• Reconstruct Shoulders for Traffic
• Emergency Pullovers every ½ Mile
• Movable Barrier for Quick Deployment
• Roaming Detours for Interchange Work
Lane Rentals:
Contractor may rent lanes during some peak hours:
I- 295 NB
4-7 PM
M-F
Stages 1, 3, 5
I-295 SB
6-9AM

Innovative or Unusual Features:
• One sided highway closures to maximize
speed and quality of construction
• Roaming detours to facilitate accelerated
interchange and mainline reconstruction
• Lane rentals to allow contractor to weigh
construction efficiencies versus costs
Risks:
• Accelerated Construction Schedule
• Public Reaction to Lane Closures
