A public hearing is being held to provide an opportunity to ask questions of Caltrans staff and Project team members regarding design features before the final design is selected, and to also provide an opportunity to ask questions regarding the planned schedule for the proposed Project, including when potential acquisition of right of way may occur and when the Project will be constructed. The public hearing location has been changed.  The public hearing, in an open house format, will be held at Sunnymead Elementary School, 24050 Dracaea Avenue, in Moreno Valley, CA 92553.  The public hearing will still be held on Thursday, July 31 from 6 p.m. to 8 p.m.
The California Department of Transportation (Caltrans) is proposing to construct an eastbound truck climbing lane and a westbound truck descending lane, and inside and outside standard shoulders in both directions on State Route 60 (SR-60) in Riverside County between Gilman Springs Road, Post Mile (PM) 22.10 and Jack Rabbit Trail PM 26.50

Caltrans is the lead agency under the California Environmental Quality Act (CEQA) and under the National Environmental Policy Act (NEPA).

The Initial Study with Proposed Mitigated Negative Declaration  / Environmental Assessment, as well as the related Technical Studies, are available for review and copying at the Caltrans District 8 Office, 464 West Fourth Street, San Bernardino, California 92401 on weekdays from 8:00 a.m. to 4:00 p.m.  In addition, it is possible to view and copy the Initial Study with Proposed Mitigated Negative Declaration  / Environmental Assessment, as well as the related Technical Studies, by visiting:

The proposed project area is in mountainous terrain with numerous tight radius horizontal curves, short tangent or connecting sections, steep grades, and swift changes in elevation.  The sustained uphill grade exceeds 2.9 percent.  A few locations have uphill grades that exceed 6 percent.  The overall change of elevation from one end of the project to the other is a little greater than 500 feet over a distance of 2.5 miles. Due to the mountainous terrain and the presence of a concrete median barrier, the horizontal alignment of the roadway is also restricted with little or no existing shoulder width.  This is true particularly on the left side of the travelled way where there is no inside shoulder for much of the project limits. The project is located in Riverside County on SR-60 between Gilman Springs Road, Post Mile (PM) 22.10 and Jack Rabbit Trail PM 26.50.  The total length of the project is 4.4 miles.  Within the limits of the proposed project, SR-60 is a  conventional two-lane, undivided highway with two 12-foot lanes and 2- to 4- foot non-standard shoulders.  The purpose of the proposed project is to improve safety, reduce traffic congestion, improve freeway operational problems resulting from trucks travelling uphill grades losing speed impeding traffic flow reducing the capacity of the highway to carry traffic.  The project would also address the non-existence of standard shoulders at numerous locations throughout the project area by providing standard shoulders.

Project Alternatives Being Studied

There are two viable alternatives under consideration, and two alternatives that were withdrawn from consideration during preliminary studies.  Alternatives 3 and 4 were withdrawn from consideration during preliminary studies because they did not adequately address the purpose and need of the project.  The total project capital construction cost varies between $72.5 million and $98.5 million.    More information on project costs is included in Table 1 on p. 1.The alternatives under consideration include the following:

Alternative 1: No-Build:

The No-Build alternative would maintain the facility in its current condition.  No improvements would be implemented at this time; therefore, no capital cost is associated with this alternative.  As development continues and traffic demand increases, traffic operational characteristics will further deteriorate resulting in an increase in congestion, vehicle delay, safety issues, and vehicle-operating costs.  The No-Build alternative would not address or alleviate the forecasted operational and safety issues along this segment of SR-60.

Alternative 2:

• Construct an eastbound truck-climbing lane, a westbound truck-descending lane and construct standard inside and outside shoulders.
• Widen and grade the area adjacent to the truck lanes and shoulders to the ultimate freeway condition.
• Rehabilitate the existing #1 and #2 lanes as well as the inside shoulder, in each direction.  The rehabilitation effort will be designed under a separate contract, and funded under a separate State Highway Operation Performance Program (SHOPP) project under Expenditure Authorization (EA) (1C090).  Both contracts are to be combined prior to commencing the construction phase.
• Reconstruct the existing concrete median barrier for the entire project.
• Most of the widening for this alternative would be to the outside of the existing roadbed.  However, for the portion of the freeway between PM 24.3 and PM 25.7, consideration would be given to widen to the median, if feasible.
• The project design will include shifting the horizontal alignment within the widened portion to improve design sight distances, where feasible.
• The project design will include modifying vertical profiles at feasible locations to improve sight distances.
