The Deadwood Box is a concrete box / bridge that supports Highways 14A & 85 and carries Whitewood Creek beneath the highway.

This study will evaluate alternate options for the replacement of the structure and roadway corridor. This is an important undertaking to replace the aging structure while accommodating the traveling public and protecting the City of Deadwood’s rich history.

Study Area

Like most buried treasure or hidden infrastructure, Deadwood community members and visitors will likely be surprised to learn there is a structure underneath US14A/US85 carrying Whitewood Creek from Pine Street to the vicinity of Tin Lizzie Casino. This map illustrates the area where the box currently sits.

A project this significant to the City of Deadwood requires a lot of planning. A Study Advisory Team will work closely with the public to develop a comprehensive plan. The study area is outlined on this map.
