CO/RTE/PM-KP 06-Fre-41-KP R48.90/R51.8 (PM R30.4/R32.2)
EA 06-419600
Project Limit NB On from East Herndon Ave. to El Paso Avenue UC.
Project Description The scope of work will consist of adding a median lane, beginning at the El Paso Ave UC and continuing to approximately 700 m north of the Audubon Drive OC. Work will also include an auxiliary lane beginning at the NB On-ramp from WB Herndon Ave, and a second auxiliary lane beginning at the Alluvial Ave UC. The two auxiliary lanes will exit at the NB Off-ramp to Friant Road and no through lanes of traffic will be allowed to exit the freeway. In addition, the NB Off-ramp to Friant Road will be widened to five lanes at the intersection with Friant Road. Four structures will also be widened to accommodate the auxiliary and median lanes.

A. The project includes the following:

(Check all applicable type of facility closures.)

Close highway or freeway lanes Highway or Freeway Lanes
Close highway or freeway shoulders Highway or Freeway Shoulders
Do not close freeway connectors Freeway Connectors
Close freeway off-ramps Freeway Off-ramps
Close freeway on-ramps Freeway On-ramps
Do not close local streets Local Streets

B. Are there any construction strategies that can restore existing number of lanes?

Yes     No  X  (Check all applicable strategies.)

No temporary roadway widening Temporary Roadway Widening
Structure Involvement? Yes     No     If "Yes", notify Project Manager.
No lane restriping Lane Restriping (Temporary narrow lane widths)
No roadway realignment Roadway Realignment (Detour around work area)
Median or right shoulder not used Median and/or Right Shoulder Utilization
HOV lane not used as a temporary mixed flow lane Use of HOV lane as a Temporary Mixed Flow Lane
No staging alternatives Staging Alternatives (Explain Below)
