Traffic and Bridge Operations

Note: In July 2021, USACE began the Phase 2 dike project to expand the CDF exterior dikes by 11 feet to maintain sufficient storage capacity for the intended project life, consistent with the original project authorization and plan. Dredging is not being performed while construction is underway. As a result, PID monitoring and turbidity monitoring are on hold. Real-time air monitoring continues in temporary locations off dike at onsite northeast and southeast stations using the M1 and M2 monitors (AM1 and AM2). The M3 and M4 monitors are not operating during dike expansion. Ambient air monitoring continues in one southwest location off dike (CON-SOUTH) and at the school. Dredging activities are anticipated to resume in 2024. More information »

Bridge Detours

Dredging operations require that bridges open to allow barges to transport dredged materials to the CDF. This may impact vehicle traffic during dredging.

When driving on Indianapolis Blvd and the bridge is up, we recommend that you turn on one of the following streets:

  • Columbus Dr (141st St)
  • Gostlin St (145th St)
  • W Chicago Ave (Rte 312)

Bridge Operations

Bridge openings are coordinated by direct communication between the tug captains and the bridge operators. The bridge operator opens the bridge as the tug and barge approach. The bridge is closed as quickly as possible once the tug clears the bridge to minimize traffic disruptions. Bridge openings are usually less than 10 minutes each.

Due to vehicle traffic on Indianapolis Blvd, the Indianapolis Blvd Bridge will not open for tug and barge traffic 5:45 AM to 7:45 AM and 3:15 PM to 4:45 PM, Monday through Friday.

The Indianapolis Blvd Bridge is expected to open approximately eight to 12 times for every 24-hour period. The schedule provides that less than half of the bridge openings will occur during heavier daytime, weekday traffic periods. The Dickey Road Bridge has some bridge openings due to barge traffic, and the dredging operation will add the same number of openings to Dickey Road as to Indianapolis Blvd.
