In the remote wilderness of Southern Alaska, innovation meets determination. 

The Juneau Creek Bridge, spanning an impressive 951 feet (290 m) is set to become one of the largest infrastructure projects in the state, transforming traffic flow and safety along the Kenai Peninsula.

They have cranes on both sides of the ravine.

AK-1 gets very congested with tourist traffic in Cooper Landing. The purpose of the new highway is to provide a bypass around Cooper Landing for traffic, especially trucks, going to the rest of the Kenai Peninsula.

And some big rigs are used to drill the piles for the bridge piers.

I'm glad to see at least one wildlife crossing.

When I accessed the satellite image, they had the launch foundation and two gantry cranes built.

And they have one of the crawler cranes assembled in a staging area.

The wildlife crossing is an underpass.

I've been looking for an image that has people to provide scale for the girders. In fact, this video specifies that they are 13'3" (4m). The bridge uses 45 girders. This photo also shows that the tires on the gantry cranes are as tall as a person.
