Oregon Iron Works, one of three companies that would be negatively impacted by the lower bridge height of a new Columbia River Crossing bridge, is close to reaching a deal that would allow it to remain at its Vancouver location, the company said Tuesday.“Oregon Iron Works is in the final phases of reaching a mitigation agreement with Oregon and Washington on the impact that the height of the (Interstate 5) replacement bridge will have on our business,” the company said in a written statement. “We are optimistic about reaching an agreement that will enable Oregon Iron Works to maintain and strengthen our operations at the Columbia Business Center in Vancouver.”Ann Lininger, an Oregon Iron Works executive, declined to comment on how soon that agreement may be finalized. The mitigation negotiations are bound by a nondisclosure agreement.The existing I-5 Bridge lift span allows 178 feet of clearance for ships when the bridge is lifted. As proposed, the CRC would allow 116 feet of clearance. Oregon Iron Works and two other companies — Thompson Metal Fab and Greenberry Industrial — say they’d be hurt or even displaced by the CRC as planned because they would no longer be able to ship some massive projects by barge. However, they publicly support the CRC and could benefit from its construction.Gov. Jay Inslee raised the prospect of mitigation on Monday, saying the CRC was close to reaching a deal with one company, which he did not name.
