Extended Lane Reductions Scheduled for State Route 49
Caltrans is alerting motorists about upcoming extended lane reductionsalong State Route 49 (SR 49) at Lone Star Road this weekend as construction continues on a $38 million safety barrier and roundabout project.
Crews will reduce northbound and southbound SR 49 to one lane in each direction from7 p.m. Friday through 3 p.m. Monday, June 9. After the extended lane reductions, two lanes will remain open northbound and one lane southbound at the intersection of Lone Star Road until further notice.
Only right-hand turns from Lone Star Road onto SR 49 will be allowed during this time. Left-hand turns onto Lone Star Road from SR 49 will be prohibited. Motorists will detour northbound or southbound to the next legal U-turn as needed.
Southbound SR 49 will also be reduced to a single lane at the intersection of Lorenson Road/Florence Lane starting today until further notice. Additional lane reductions are scheduled in August at the intersection of Lorenson Road/Florence Lane and in September at the intersection of Lone Star Road.
The extended lane reductions are necessary to allow room for crews to continue working safely on the new roundabout. Motorists may experience delays between 10 and 15 minutes, depending on traffic volumes.
The schedule is subject to change or be delayed due to weather, availability of materials or other unexpected events. The work zone speed limit has been reduced to 45 mph 24/7 for the safety of workers and the traveling public. The California Highway Patrol will be present for traffic enforcement and motorists are reminded that traffic fines are doubled in construction zones.
DeSilva Gates Construction of Dublin is the prime contractor. The project is expected to be completed by fall of this year. At that time, the 1.3-mile stretch along SR 49 will include a concrete median barrier and roundabouts at the Lorenson Road/Florence Lane and Lone Star Road intersections. Additional work will include new pavement, striping, curb gutters, sidewalks, lighting and signage.
Caltrans District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties. Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements. Please reach out if you have any questions.
