It is not that we have too many bridges crossing the Columbia River in our area, congestion being some of the worst in the nation at night.

What justification has been presented to remove federally protected bridges? National

Significance category as a marvel engineering feat of its time. The bridges that serve our communities with pride daily.

We do not need to remove the I-5 bridges to construct a new modern multi-modal bridge. A supplemental bridge gives construction jobs too. So again, why are we

REMOVING the I-5 bridges when adding capacity across the Columbia River is the project?

The bridges need better bike and pedestrian crossing. So add a promenade that is historically appropriate with the view of Mt. Hood.

The seismic upgrades are very doable and have been done on several bridges in our area.

We are still waiting for a complete independent report from a company that specializes in bridges seismic upgrades to inspect and evaluate the I-5 bridges.

A panel of experts in 2006 CRC EIS said upgrades to save the bridge could be done. New ground liquidation stabilization techniques are a game changer. Costs the panel quoted were very reasonable considering the bridges’ in 2005 valued at approximately a billion dollars.

The bridges are overcapacity. So is the I-5 freeway leading up to the bridges. The adjacent neighborhoods funnel traffic, through their neighborhoods as vehicles rush to one of only two bridge crossings in an area identified as needing additional crossings since the 1990s.

The bridges are doing more than their part moving traffic. A rating size is 88,000 vehicles and they carry 140,000 daily. Again the bridges are not the problems. They are our work horses, solid and true. More bridges, less traffic on the I-5 freeway and the overcapacity of I-205 bridges. That’s how math works, more bridges less congestion

That is a good reason to keep the bridges and add more crossings right?

The lift on the bridges? Is that really a problem? A second lift added to the BNSF rail bridge aligned with the I-5 bridge barge channel means 95% less lifts, approximately 30 lifts in a year. On the same rail line in 1989 crossing the Willamette River, the largest swing-span section in the world was replaced with a new lift in 72 hours. Doable and necessary for safety if we keep our bridges or construct a replacement bridge. Think about that.

Keeping the lift height on the I-5 bridges for current and future marine traffic.
A supplemental bridge 1-mile west, adjacent to BNSF rail bridge, the center of the project area has no impediments to airports and marine terminals.
Add capacity to a supplemental bridge UNLESS the I-5 bridges require replacement.
