CALIFORNIA STATE ROUTE 79
FREEWAY CONVERSION PROJECT
CONSTRUCTION STAGING
OVERVIEW
The SR 79 Freeway Conversion consists of six construction phases. The order of these phases were chosen to minimize the impacts to traffic , the surrounding communities, and the overall cost of the project. Before zooming in to each phase let's take a look at the screen to get familiar with how the phases are divided. The first 3 phases involve changes to the Northern portion of our project from 1st street to a meeting point 2 miles away from California Ave. Phase 4-6 involves the changes from the meeting point to Gilman Springs Road.
PHASE 1
This image shows the changes that occur in Phase 1. The parts seen in blue are included in this phase, and the items seen in grey are not included in this phase. On the left side are the existing conditions and on the right side is what is built once the phase is complete. Phase 1 consists of the realignment and expansion of the existing northbound lanes from 2 to 3 lanes from California Ave to approximately 2 miles south of California Ave. In addition, the construction of the East side On and Off Ramp as well as the start of the California Ave bridge construction will take place. Lastly, the construction of Laird Road will occur.
PHASE 2
Phase 2 consists of the realignment and expansion of the existing Southbound lanes from 2 to 3 lanes from California Ave to approximately 2 miles south of California Ave. The construction of the West side On and Off Ramp as well as the end of the California Ave bridge construction will take place. Lastly, the construction of the access and frontage road will be constructed.
PHASE 3
Phase 3 consists of the bridge construction at First Street as well as the realignment and expansion of the lanes from first street to California Ave.
PHASE 4
Phase 4 consists of the realignment and expansion of the existing northbound lanes from 2 to 3 lanes from .5 miles North of Lamb Canyon to 2.5 miles South of Lamb Canyon. The construction of the East side On and Off Ramp as well as the start of the Lamb Canyon bridge construction will take place.
PHASE 5
Phase 5 consists of realignment and construction of the southbound lanes .5 miles North of Lamb Canyon to 2.5 miles South of Lamb Canyon. The construction of the West side on and off Ramps, and the end of the Lamb Canyon bridge construction will take place. Lastly, the start of the shared use path will begin.
PHASE 6
Finally, Phase 6 consists of the realignment and expansion of lanes starting 2.5 miles south of Lamb Canyon to Gilman Springs Road. The end of the shared use path and the construction of the animal crossing will occur as during this phase.
