Intersections and choke points

• Consider two lanes of traffic in each direction and LOS at E or F.
• Investigate necessary vertical profile changes; current clearances do not meet today's standards. (Note that roadways will have to be dipped for vertical clearance.)
• Determine whether the current shoulders are full depth or whether they will need to be improved to put traffic on.
• Consider temporary pavement.
• Widen alternate routes, and improve intersections with the cooperation of local entities.
• Note: The ACHD operates signals on the State system and manages all ROW not controlled by ITD.
• Need two lanes open to through traffic during peak hours.

• Add a third and later a fourth lane.
• Set up temporary lanes with design exceptions such as four foot shoulders in the median.
• Determine how long ITD can wait with the current bridges.
• Consider a reversible lane to address eastbound morning traffic and westbound afternoon traffic.
• Improve local roads such as Gowen and Franklin to help with traffic during construction.
• Develop staging plans and consider having only one lane open to traffic from Gowen to Isaac's Canyon. Consider directing larger vehicles onto alternate routes.

Managing traffic

• Determine major destinations and evaluate alternate commuter options.
• Promote public transportation.
• Install traffic cameras or micro traffic loops for instant management of traffic, VMS and 511. Utilize ITS systems.
• Look at crossovers and how they can be used.
• Analyze potential bridge and interchange closures and how long it will take to open new bridges.
• Plan ahead for other projects along the route.
• Designate an incident management vehicle.
• Consider reversible lanes for rush-hour traffic.

• Look at detour options.
• Note that Park & Rides are currently maxed out.
• Work to mitigate congestion.
• Work out flex hours with private businesses, i.e., Micron, to lighten traffic by busing or varying shifts to off peak hours.
• Research existing traffic models to review possible traffic and emergency plans.
• Look at potential problems with radar detection or usage of VMS.
• Build structures next to existing before removing existing.
• Need to coordinate construction with County and/or City entities.
• Need to identify areas impacted the most by Interstate construction.

Corridor management teams

• Determine which contracts within the overall project will affect each other.
• Combine traffic control contracts.
• Consider performance based contracts.
• Research what other States have used.
• Determine priorities.

• Designate one team to coordinate a group of contracts instead of administering each contract separately.
• Provide performance based bonuses for accident counts or flow rates.
• Utilize lane rentals with prices to determine the cost effectiveness of lane restrictions.
• Maintain flexibility with regards to traffic control plans. (Who will monitor this?)
• Try to keep the route open at all times or during peak traffic hours.
• Address problems with the contractor and traffic control corridor team and determine who takes responsibility for claims.

Traffic safety for bicycle and pedestrian traffic

• Consider bike lanes on the Interstate.
• Ensure ADA compliance.

• May need to truck bikes and/or pedestrians across the work zone.

Traffic control for major events

• Plan work zone closures in advance.
• Check on events for the duration of the project.

Smart work zones

• Design ITS around the desired objectives.
• Utilize variable speed limits depending on the time of day.
• Utilize FHWA's Quick Zone program.

• Link travel times to incentives/disincentives.
• Use a money pool.
• Identify objectives and set priorities for the setup of the work zone.
• Use digital speed limit signs to vary speeds as needed.
