I-5 - NB Interstate Bridge – South Tower Trunnion Replacements

In summer 2019, crews will close the northbound span of the bridge to replace a cracked trunnion in the south tower, that raises and lowers the northbound span.

The closure will allow crews to safely bring in heavy equipment to remove and replace the trunnion, which is 20 inches in diameter and 4 feet long.
