Columbia River Crossing Project Update

In the latest project newsletter emailed by CRC staff, they’ve posted a document which shows computer-generated 3D renderings of what various bridge options and alignments might look like:

  • Supplemental bridge
  • Replacement bridge with a separate structure for transit
  • Replacement bridge with “transit in a box” in the southbound structure

(They also are sure to point out an important disclaimer: “Regardless of the bridge choice, the final look of a new bridge has not been decided.”)

The next CRC meeting: The next Task Force meeting will be held Jan. 22, 2008, at 4 p.m. at the Vancouver Hilton, 301 W 6th Street. The Task Force will not take any formal action at this meeting.

There’s also an interesting note about birds:

Oregon Department of Transportation bridge crews are using propane orchard cannons to scare European starlings from the I-5 Bridges through Friday, Feb. 29.

Each year, tens of thousands of starlings migrate to the Portland/Vancouver area. Many flocks roost on the Interstate bridges—particularly the lift spans—in the fall and winter. Bird droppings coat the bridges, the catwalks, the roadway, vehicles, bicyclists and pedestrians. The mess is unhealthy, unsafe and unsightly. The cannons will operate 36 days for about two hours each day in the late afternoon and early evening.

Propane powered orchard cannons were originally designed to disturb birds in fruit orchards with a loud noise. Motorists, bicyclists and pedestrians crossing the bridges will hear the blasts, which could occur as often as every 15 seconds.

ODOT crews will not use the cannons every day. The reaction of the birds will dictate use of the cannon. Employing this random schedule will prevent the birds from becoming accustomed to a regular pattern.

In addition to the cannons, workers will use the low-tech method of banging on the steel bridge beams with hammers.
