Windsor Old Redwood Highway Improvements

Old Redwood Highway Roundabouts and Back-In Angle Parking

Old Redwood Highway Improvements

New Traffic Features Coming to Windsor

As part of the Bell Village development, major improvements to Old Redwood Highway are under construction. Two traffic features, roundabouts and back-in angle parking, which are new to the Town of Windsor, are being incorporated into the design. The following information is intended to introduce you on the operation of these traffic features. We hope navigating these features will become second nature to you as Windsor continues to grow.

Windsor Old Redwood Highway Roundabouts

Projected Timeline for Old Redwood Highway Improvements

Roadway improvements along Old Redwood Highway will be constructed in two phases. The first phase is anticipated to be completed by the end of April 2015. The limits of the first phase are from Windsor River Road to Joe Rodota Drive and include a roundabout at Market Street and back-in angle parking along Old Redwood Highway. The remaining improvements from Joe Rodota Drive to Windsor Road are currently in design and are expected to be under construction in Summer 2015 with completion in early 2016. The second phase includes a roundabout at Windsor Road and additional reverse angle parking along Old Redwood Highway.

What is a Roundabout?

A roundabout is a type of circular intersection with one-way, counter-clockwise traffic flow. Vehicles yield on entry and flow around a center island. The roundabout design features take the place of a traffic signal light and provide other benefits to safety, aesthetics, air quality and maintenance costs. Pedestrians cross one direction at a time with a median island providing refuge during the crossing. Through proper design, roundabouts can easily accommodate emergency vehicles, buses and trucks. Larger trucks will need to mount onto the apron around the central island in completing turns.

Roundabout Benefits


  • Up to 90% less fatalities
  • 76% less collisions resulting in injury
  • 30-40% less collisions involving pedestrians
Conflict Points

Slower vehicle speeds (under 25 mph)

  • Drivers have more time to judge and react to other cars/pedestrians
  • Better for elderly and novice drivers
  • Reduces the severity of crashes

More efficient traffic flow

  • More capacity per lane than traffic signal
  • By yielding instead of stopping and waiting, delay is significantly reduced
  • Intersections with a high volume of left-turns are better handled by a roundabout than a multi-phased traffic signal (and the less idling, the better for the environment!)

Saves money

  • No signal equipment to install and repair
  • Approximately $5,000 saved per year in maintenance costs
  • Service life of a roundabout = 25 years
  • Service life of a traffic signal = 10 years

Other Benefits

  • Traffic calming
  • Less vehicle air emissions than traffic signals
  • Central island makes room for aesthetic landscaping

Navigating a Roundabout


  • Slow down on approach.
  • Yield to pedestrians in the crosswalk, they have the right of way.
  • Upon entering, yield to vehicles already in the roundabout. Merge in when it is safe.
  • Continue until you reach your exit. Do not stop or pass.
  • If an emergency vehicle approaches, exit immediately and then pull over – do not stop in the roundabout.
  • When exiting, signal your turn and yield to pedestrians.   
Roundabout Explained


  • Cyclists can either ride with traffic inside the roundabout or use the crosswalks appropriately.
  • Cyclists who ride with traffic must follow the same rules as vehicles. With slower vehicle traffic, experienced cyclists should be able to travel at or near the same speed as motorists.


  • Cross only at crosswalks, and stay on the walkways.
  • Never cross to the central island.
  • Cross the roundabout one approach at a time.
  • Use the splitter island as a halfway point where you can check for traffic.

Back-In Angle Parking

How do you BACK-IN angle park?

  1. Signal when slowing to approach the space
  2. Pull past space
  3. Back into space on angle
Back-in Parking

Benefits of BACK-IN angle parking

  • Better motorist’s vision of bicyclists, pedestrians, and other vehicles as they exit a parking space and enter moving traffic
  • Eliminates car door-bike conflict
  • Protection for children because the open car door directs children away from the street
  • Easier than parallel parking
  • Increased parking capacity

A number of cities that have installed back-in angle parking including: San Francisco, San Jose, and Chico in California, Seattle, Tacoma, Olympia, and Vancouver in Washington; Portland and Salem in Oregon; Tucson, Arizona; Austin, Texas; and Washington, D.C. Tucson tracked data for bicycle/car crashes before and after installing back-in angle parking, and found an average of three to four crashes per month with front-in angle parking compared to zero reported bicycle/car crashes for the first four years following implementation of back-in angle parking.
