| Full closure |
Change in bus service (both mass transit and school) along closure and detour routes. |
Pre-project meetings and coordination. |
|
Model traffic flows to determine best detour routes. |
Simulation will help the public better visualize the different options and results. |
|
Incident management plan to mitigate congestion due accidents and breakdowns. |
Coordination with local law enforcement, emergency services, and DOT. Courtesy patrols. |
|
Improvement to detour routes and intersections to handle additional traffic. |
Additional turn lanes, optimize signal timing, preventive maintenance on signal equipment, change parking restrictions, additional parking enforcement assets. Possible ADA improvement requirements for intersection improvements. |
|
Use variable message signs to detour commuter traffic in advance of project detour routes. |
|
|
Project website for real time traffic information and detour routes. |
|
|
Pedestrian access. |
Additional lighted pedestrian walkway and foot bridge. Shuttle bus for school students |
|
Allows additional staging area for equipment on existing closed road. |
|
|
Safety. |
Better safety at construction site. Increase in accidents due to additional traffic along detour routes. |
|
Truck route. |

AGC Constructability Review. |
|
| Phased Construction |
Better local access (pedestrian, bus, vehicles). |
Less disruption. Mixed safety concerns (more accidents at construction sites, less at detour). |
|
Traffic capacity will be cut in half. |
Alternate route development and signing. |
|
Incentives for contractor to accelerate construction. |
Lane rental, A+B contracting, incentive/disincentive contracting. |
|
Incident Management Plan. |
|
|
Truck Routes. |
|
|
Pedestrian access. |
Pedestrian access under bridge. Build new pedestrian route. |
|
School access. |
|
|
Staging area for contractor. |
Additional environmental considerations. |
