Windsor River Road/Windsor Road Intersection Improvement Project (Roundabout)
The Windsor River Road/Windsor Road Intersection Improvement Project will transform a signalized intersection to a roundabout, improving safety and efficiency for motorists, cyclists, and pedestrians. This project, which will be constructed in six stages, started August 23, 2021, and will be completed in about one year. For background information, please go here.
The hours of construction will be 7:30 AM – 5:30 PM, Monday-Friday, exclusive of holidays. For more information, call the Town of Windsor Public Works Department at (707) 838-5340.
01/06/2022: On Tuesday, January 11, Ghilotti plans to replace a storm drain manhole on Windsor River Road, west of Windsor Road which will require single lane traffic control with flaggers. Work will begin after 8:30a.m. when school is in session and should be completed within the day but may go through the school dismissal time.
During PG&E work last month, utility conflicts were discovered with Sonic cables. Sonic will be onsite Saturday, January 8 to relocate their facilities. All work will be within the barricaded construction area. Ghilotti will be back on the job on Monday, January 10 and expects to complete fire hydrant, storm drain, grading, remaining curb and gutter and other concrete work over the next three weeks.
12/14/2021: Flashing beacons have been installed at the temporary crosswalk east of the construction site on Windsor River Road to help pedestrians and cyclists cross safely. PG&E completed re-lowering its gas-service lines to accommodate the storm drain pipe and in the upcoming week, the contractor is scheduled to install the aggregate base for concrete as well as install curb, curb ramps and sidewalks.
11/03/2021: Overnight construction work on November 4 - Comcast will relocate its overhead facilities at the roundabout site between 11 PM on Thursday, Nov. 4, and 6 AM on Friday, Nov. 5, to a new underground vault. This night work will minimize internet/CATV service disruption to the community as the company will take down coaxial and fiber circuits.
10/19/2021: Current construction site activity consists of utility relocation of facilities by Comcast, AT&T, and PG&E. There has been a delay in storm drain pipe material shipments so underground work is expected to resume at the end of the week. Ghilotti Construction is preparing the site for rain/storm events and all work is weather permitting. Pedestrian activated flashing beacons are on order and is expected in to be installed at the temporary cross walks on Windsor River Road in three weeks. Until that time, Ghilotti Construction is providing flaggers at the temporary crosswalks, Monday through Friday, during peak school traffic hours in the morning and afternoon.
09/23/2021: The Windsor River Road and Windsor Road roundabout construction project is on track and current upcoming work in the next few weeks include excavating and subgrading the roadway, installing electric conduits, irrigation chases, and railroad conduits, and removing storm drains.
Also, as many of you know, concrete barricades and temporary vehicle and pedestrian detours – including two pedestrian crosswalks east and west of Windsor Road – are in place. Please follow these detours to help keep everyone safe.
08/24/2021: The contractor will place the traffic signal in red flash (all-way stop) at 10 AM for several hours on Wednesday and Thursday, August 25-26, for temporary striping modifications and placement of K-rail barriers.
08/19/2021: The contractor will start setting up and prepping the construction site on Monday, August 23, so the traffic detours will not go into effect until Wednesday morning, August 25. We will monitor traffic control and modify as necessary throughout the project.
Stage I Summary
- Set up staging area for storing supplies and equipment on the vacant lot that is located on the southwest corner of the intersection.
- Set up barricades and detours to allow the closure of Windsor Rd from Windsor River Rd to the south entrance of Marshall Way.
- Demolition of existing curb, gutter, sidewalk, and pavement in the work zone.
- Construction of new improvements in this work zone that will align with the northerly leg of the proposed Roundabout.
The Roundabout Project will improve vehicular, bicycle, and pedestrian circulation at the Windsor River Road (WRR) and Windsor Road (WR) intersection by replacing the existing signalized intersection with a roundabout and completing a segment of a multi‐use pathway.
Pedestrian crossing safety improvements include new sidewalks, realigned crosswalks, ADA curb ramps, and refuge medians. The project also includes a 760 linear‐foot segment of the Class I SMART multi‐use path alongside the rail line.
Stage 1 of the construction project will include all improvements between WRR north to Marshall Way. WRR will be closed to vehicular traffic north and south between Marshall Way and WRR. Pedestrian access to businesses along this stretch will be maintained. Pedestrian access through the intersection will be maintained however temporary crosswalks will be used to get them safely through the work area.
All other segments of the intersection will remain open during Stage 1. Vehicles will be able to travel east and west on WRR. Vehicles will also be able to go south on WR. North bound vehicles on WR will have to make a right or left turn at WRR.
If you plan on using this intersection during construction, please allow yourself more time to get to your destination in case of delays. As always, please watch for pedestrians, bicycles, and workers in the area and obey all the traffic control signs.
