CANYON FERRY DAM

TEMPORARY TRAFFIC CONTROL STATEMENT OF WORK

PART 1 GENERAL

1.01 INTRODUCTION

The Canyon Ferry Dam was constructed from 1949-1954. The Bureau of Reclamation constructed and continues to operate and maintain Canyon Ferry Dam.

The Bureau of Reclamation plans to clean the drains located within the dam. To accomplish this work, specialty equipment must be staged along the dam crest during working hours. Montana Highway 284 crossed the crest of Canyon Ferry Dam. The staging of this equipment will require one lane of that highway to be closed while work is occurring.

The proposed project consists of performing all necessary work to efficiently provide an automated traffic control system that automatically controls traffic through an open single lane. It also requires that the system be set up and Bureau of Reclamation employees be trained in how to control the system.
