The Bridge Inspection Report is attached as Exhibit A; and WHEREAS, a deck rated as 4 (poor condition) is classified as "structurally deficient;" and WHEREAS, the Eagle County Engineering Department has contracted with Ewing Trucking and Construction, LLC ("Contractor") for the replacement of the Gypsum Creek Bridge due to the structural deficiency; and WHEREAS, Contractor will require a complete road closure to replace the Gypsum Creek Bridge for the safety and protection of work crews and road equipment; and WHEREAS, C.R.S. § 42-4-106(6)(a) provides that local authorities may temporarily close Colorado roads or highways by resolution stating the closure is necessary for the safety and protection of work crews and road equipment. NOW,THEREFORE,BE IT RESOLVED BY THE BOARD OF COUNTY COMMISSIONERS OF THE COUNTY OF EAGLE, STATE OF COLORADO: THAT, Cottonwood Pass Road shall be closed to all traffic, including but not limited to pedestrian traffic, bicycle traffic, and vehicular traffic. The closure is necessary for the safety and protection of Contractor's work crews and road equipment; THAT, the location of the closure and the detour for Cottonwood Pass Road is indicated on the detour plan from the approved project plan and is attached as Exhibit B. The duration of the closure is anticipated to take place from April 1, 2022 to June 30, 2022. These dates may vary based on field conditions and project progress; THAT, Contractor will be required to notify emergency services and service providers in the area prior to the closure. The contractor will coordinate with the Eagle County Communications Department to issue a News Release prior to the closure; and DocuSign Envelope ID: 19B7F519-8293-473F-9397-7C9F3E7E04F4 THAT, the board hereby finds, determines and declares that this Resolution is necessary for the public health, safety, and welfare of the residents of the County of Eagle, State of Colorado. MOVED, READ, AND ADOPTED by the Board of County Commissioners of the County of Eagle, State of Colorado, at its regular meeting held the 29th day of March 2022.

The deck is rated as poor condition (4), classifying the bridge as structurally deficient. The bridge was last rated in 1986. The load capacity reported at the inventory level is 17.9 tons, which is based on 7-inches of asphalt on the corrugated metal deck. The W16x40 interior girder controls the load rating as it has a lower capacity than the deck (load rating summary attached, see last page). Therefore, the bridge is currently posted due to low capacity. Also note that the bridge currently has 9-inches of asphalt now, therefore the capacity is actually lower than capacity reported on the SIA. Many factors play into the sufficiency rating calculation. For this bridge, the factors which contribute to the current rating are: inventory load rating, deck condition, structural evaluation, deck geometry (width), ADT, and bridge rail. The inventory load rating has the highest impact on the current sufficiency rating. Proposed improvements outlined in the narrative would improve all conditions reported in the SIA, but would not improve the load capacity as the girders would not be replaced. The proposed improvements would however remove it's classification from being structurally deficient and also improve the sufficiency rating. Several scenarios were evaluated as shown in Table 1 on the following page. Please note that not all improvements will affect the sufficiency rating. This is because the rating for some items, such as substructure and channel protection, are not currently low enough to result in reduction. In addition, without improving the capacity of the girders, the overall sufficiency rating will not improve by a significant amount.
