First blast drops Southern span.
The southern span of the old Route 89 bridge over the Illionois River in Spring Valley was imploded early Tuesday morning.
The bridge’s replacement, the Illinois Valley Veterans Memorial Bridge, opened in June. The new bridge provides a wider span for emergency vehicles, pedestrians and bike traffic.
The other span of the old Route 89 Bridge, which was built in 1943, will be demolished in the next few weeks.
