State Route 246 Passing LanesBackground
Project Inception:• 2001 PSR looked at a variety of alternatives to achieve the purpose and
need for the project
Project Purpose:• To improve mobility (traffic flow) by reducing the length of traffic queues• To improve sight distance at the intersection of Tularosa Road and reduce
the length and severity of the approaching grades
Project Need:• Vehicles spend 65% of their time behind slower-moving traffic during the
peak hour.• Passing opportunities are limited by oncoming traffic during peak hours• Through traffic is delayed by left-turning traffic.
State Route 246 Passing LanesBackground
Environmental Studies• In 2006, passing lanes (Alt. 2 of the PSR) were determined to be sufficient
to achieve a satisfactory level of service.• Project Alternative developed that included two sets of passing lanes and
channelization at public road intersections between Cebada Canyon Rd. and Domingos Rd. This became the preferred alternative.
• Environmental and engineering studies completed and the project approved with the preferred alternative in 2010.
• Significant mitigation for California Tiger Salamander proposed including culvert crossing and viaduct near Campbell Pond.
State Route 246 Passing LanesFull Project
State Route 246 Passing LanesMeasure A
• Measure A, passed in 2008, included $20 million for Route 246
• Full project cost was estimated at $50 million - significant additional STIP funding was needed to implement
• Strategic Plan development identified a way to implement project in phases to gain near term benefits
• Caltrans concurred that western segment would provide operational benefits alone in the near term
• Eastbound passing lanes between Cebada Canyon Road and Tularosa Road
• Westbound passing lanes between Hapgood Road and Tularosa Road
• Intersection improvements including left-turn channelization at:• Tularosa Road• Hapgood Road (west)
• Realign roadway and lower the profile at Tularosa Road

Project Status• Environmental Document approved June 2010
(Will be revalidated during PS&E with changed limits)• Right of way acquisition, permitting and mitigation bank
credits for California Tiger Salamander being negotiated• Cooperative agreement between Caltrans and SBCAG
being prepared.• Early summer 2014: Ready to list for advertisement• Fall 2016: Roadway construction complete• Winter 2019: Planting and mitigation complete
