2050 Transportation Network Sustainability Plan

The Washington County Highway Department has developed its first long-range transportation plan. The plan has a design year of 2050 and serves as a guide for budgeting by estimating when specific stretches of the Washington County highway system should be improved based on a 25-year pavement lifecycle. This plan is intended to help achieve a financially sustainable transportation network for Washington County. This plan serves as a guide and information within it is subject to change due to many factors in the future.

Washington County Highway Department Projects

Washington County road construction is prioritized on the basis of need and roads are built with federal aid if possible with contracts let to the lowest bidder. See the map below for the County's 5-year Highway Improvement Plan for 2019-2024. The Department's long-range road improvement plans are detailed in its 2050 Transportation Network Sustainability Plan. All County and State projects displayed are subject to change.

5-Year Highway Improvement Plan (2019-2024)

Safety is also a primary factor when determining which roads should be improved. Washington County's GIS division has produced the following accident severity map that summarizes where roadway accidents have occurred throughout Washington County from 2014 to 2018 and how severe they were. This information is a key component when determining where safety should be improved on Washington County's highway system.

Roundabout at CTH Q and Hillside Road

Washington County is planning to apply for funding to construct a roundabout at the intersection of CTH Q and Hillside Road. This intersection is on the borders of the Village of Richfield (Washington County) and Town of Lisbon (Waukesha County). There has been a history of crashes at this intersection. Utilizing crash data from 2013 to 2017, Washington County's Intersection Safety Analysis confirmed the intersection has a high number of crashes (30) and high crash rate (1.468) ranking it 4th and 11th in each category respectively among all county-controlled intersections in Washington County. Information specific to this intersection can be found on pages 11, 12, 14, 18, 20, 23, 24, A-1, B-1, C-1, and D-20 thru D-24 of the analysis.

A public informational meeting (PIM) was held on Wednesday, July 31st at the Richfield Village Hall to present and discuss the proposed improvements. The following links provide additional information regarding the PIM and roundabout project:

  • Massive supports such as telephone poles, heavy metal posts, concrete posts, antique farm equipment, or other similar items are prohibited. Any support must be designed so that if it is struck, it will bend or fall away from the striking vehicle to prevent severe damage to the vehicle or injury to the traveling public. If possible, all newspaper tubes and mailboxes shall be placed on the same post to avoid unnecessary posts.

  • Nothing shall be attached to the mailbox, newspaper tube, or its support.

  • Use of a semi-arch or extended arm-type support which allows snowplows to sweep near or under mailboxes without damaging supports is recommended.

  • When newspaper tubes are used other than those provided by the newspaper, the Highway Commissioner shall have the exclusive authority to approve the newspaper tube.

  • The Washington County Highway Department will repair or replace mailboxes that are physically struck by a county highway department truck.  A standard size and design box will be used. We will not repair mailboxes damaged by snow.

  • Please see Washington County Code, Chapter 12.04

  • Mailboxes should be mounted at a height of 41 to 45 inches from the road surface to the bottom of the mailbox or point of mail entry.
