I-495 Northbound and Southbound Closed
at Bridge 1-813 over the Christina River Wilmington – The Delaware Department of Transportation (DelDOT) has announced an
immediate closure of Bridge 1-813 over the Christina River on 1-495.
DelDOT is closing the bridge today because an inspection showed four of the 37 support
columns are tilted as much as four percent out of vertical alignment. The bridge is closed
as of 6:00 p.m. today. This will cause a significant impact to the traveling public, and we
are coordinating with local, state, and federal partners to provide information as we receive
it. Our bridge engineers and consultant are on the scene and are placing tilt sensors to
monitor the bridge.
I-495 will be closed northbound at Terminal Avenue and message boards are in place on I-
95 and SR 1 and Rt. 13. Local northbound traffic can stay on I-495 to Terminal Avenue. I-
495 southbound will be closed at the Pennsylvania State Line. Southbound traffic will be
directed to take I-95 southbound.

Recurring Congestion This is the type of congestion where there are simply more vehicles than the roadway can
accommodate. Recurring congestion occurs during peak travel periods for a simple reason – the number of vehicles trying to use the highway system exceeds the available capacity.
• Recurring congestion: predictable ◦ Daily rush hour
◦ Summer beach traffic
12
Non Recurring Congestion “About half of congestion is caused by
temporary disruptions that take away part of the roadway from use – or "non-recurring" congestion.” (FHWA, 2011)
•Non-recurring congestion: unpredictable disabled vehicle debris on roadway vehicle accident flooding natural disaster
The likelihood of a secondary crash increases by 2.8 percent for every minute that the primary incident remains a hazard. (ITS Journal)
Transportation Management Center (TMC)
• 24/7 Statewide Operation
• Coordinates and Manages DelDOT’s response to any incident or event that impacts Delaware’s multimodal transportation system
• Monitors and Controls all ITMS intelligent transportation systems
• Transportation Incident and Emergency Management Planning and Operations
• Transportation Homeland Security Planning and Operations
– The TMC is part of the Statewide Emergency Operations Center
– The State EOC includes:
• Delaware Emergency Management Agency
• Delaware State Police
• Delaware Department of Transportation

• Did the tow truck arrive?
• Have conditions changed?
• Adjust traffic signals to manage the
detour route
• Staff on scene to control traffic
•
• Is the public informed?
• Have conditions changed?
The TMC Performs Three Critical Functions
Priority: Expand and enhance monitoring system.
Monitoring System Requirements Defined by Planning and Operations Committee

Weather • Air Temperature • Barometric Pressure • Relative Humidity • Precipitation Type & Volume • Pavement Temperature • Subsurface Temperature • Pavement Surface Dry, Wet, Ice • Stream & River Depth and Velocity • Tide Height •
Traffic • Traffic Volume • Occupancy (Delay) • Speed • Classification • Travel Time • Origin and Destination •
• Real-time
• Predictive
Monitoring System Statewide Electronic Monitoring Network – Fixed and Portable:
– Video Monitoring System
– Permanent
– Portable
– Dash Cams (Live Video)
– Roadway Weather Information System (RWIS)
– Signal System Loop Detectors
– Microwave (Radar) Detection on Freeways
– Bluetooth Detection (started Summer 2013) Installation of over 100 sites FY15/16
– Railroad Crossings
– Near real-time transportation system status
– Hydrology monitoring system Phase 1 FY15

DelDOT is focusing on Smartphone's and tablets…
We have to be smart enough to quickly adapt to the changes in information technologies…..
We need to embrace and integrate social media, crowd sourcing, and the transportation system user community into a two-way information stream.…..
Priority:
Traffic responsive signal operations
• TACTICS Conversion
• Multiyear Corridor Program
• Evacuation Routes
Transit Schedule Adherence
and AVL System
• Fixed Route
• Para transit
• Bus Stop Electronic Message Signs
• Web
•DelDOT App
Priority: Transit Schedule Adherence System
44
Priority: Transportation Homeland Security and Incident Management
• Partnerships and Relationships
– Continue Improving Transportation Management Teams
– Continue Regional Coordination
• I95 Corridor Coalition
• Integration with adjoining states (MD, PA, NJ)
– Event Planning
45
Priority: Transportation Homeland Security and Incident Management
• Training for TMC Staff
• DEMA / DEOP Support
• Homeland Security
• Training / Exercising DelDOT 1st Responders

Return on Investment (ROI)
• High Cost:
– Roadway Widening/Reconstruction
• Low Cost:
– Signal Retiming and phasing
