What river flows under the Astoria-Megler Bridge, pictured here?
A Colorado River
B Columbia River
C Snake River
Ships traveling the Columbia River pass under the Astoria-Megler Bridge, next to Astoria, which spans the river’s mouth between Oregon and Washington. They share the water with salmon that use the river and its tributaries to spawn, and the seals and sea lions that wait for the salmon with hungry bellies at the mouth of the river.
The correct answer is Columbia River.
