Delaware River Turnpike Bridge Best Scenario:

 No settlement and confirmation that this is an isolated finding  Material testing across entire structure does not show global issue  The structural members move as predicted during slow, regulated jacking  Sensors installed during instrumentation and analysis show that stresses shift in existing members to acceptable levels during jacking

 Permanent splice is installed  Complete repairs; load test

 Open the bridge to traffic 38
