SouthBmore reports Kiewit's contract award for the Key Bridge replacement (published 4 September 2024), noting "the new bridge expected to open in fall 2028", matching the pin's stored 1 October 2028 (fall 2028) date.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
