In August 2023, the CTC received a report of an SHOPP Safety Sub-Allocation made by Caltrans on 07/12/2023:$7,276,000. 02-Plu-36 R13.6/R14.2. PPNO 02-3759; ProjID 0219000145; EA 0J640. Route 36 Near Chester, from 0.3 mile west to 0.3 mile east of County Sign Route A13. Outcome/Output: Improve safety by constructing roundabout.  This project will reduce the number and severity of collisions. Preliminary Engineering (Budget / Expended): PA&ED $940,000 /  $568,612; PS&E $1,190,000 / $1,033,639; R/W Sup $190,000 / $134,183. CEQA - CE, 12/13/2021; Re-validation 6/19/2023. NEPA - CE, 12/13/2021; Re-validation 6/19/2023. Two month allocation time extension for CONST and CON ENG approved under Waiver 23-72; June 2023. Allocation Date: 07/12/2023.

In December 2023, the CTC considered a supplemental allocation of $2,210,000 (37.3 percent increase) in Construction Capital for 02-Plu-36 R13.6/R14.2, PPNO 02-3759; ProjID 0219000145; EA 0J640. Route 36 Near Chester, from 0.3 mile west to 0.3 mile east of County Road A13. Improve safety by constructing roundabout.  Outcome/Output: This project will reduce the number and severity of collisions. Supplemental funds are needed to Award. CEQA - CE, 12/13/2021; Re-validation 6/19/2023 NEPA - CE, 12/13/2021; Re-validation 6/19/2023 Total revised amount $8,136,000. In August 2023, the Department advertised the contract and held bid opening in October 2023.  The contract received three bids, of which the lowest bid is 34.1 percent above the Engineer’s Estimate (EE).  The remaining bids are 39.2 and 82.0 percent over the EE. The cost increases on this project are largely attributed to the need for four separate mobilizations of major operations and anticipated slower production rate. Risks associated with slower production are reflected in the item prices.  The bidders indicated that the roundabout paving items represent unique challenges when compared to linear operation. The EE accounted for material prices, but elevated labor costs, stemming from slower production rate and risk of rework to meet allowable tolerances, surpassed the assumptions in the EE.

In July 2024, it was reported that Caltrans continuing work on the County Sign Route A13 Route 36 Safety Project, near Chester from just east of Bailey Creek Bridge to just east of County Sign Route A13 in Plumas County. The safety project includes the construction of a traffic circle (roundabout). Constructing the roundabout includes removing the existing asphalt, performing earthwork cuts, placing asphalt concrete structural sections in the circulatory roadway and approach legs, and adding concrete curbing for the roundabout and approach legs. In addition, the safety project will relocate one utility pole, add striping and new landscaping, add luminaries on the approach legs, and install new signage. The construction project includes 85 working days, and is expected to be completed by the end of September, pending weather and operations.
