Wis. Admin. Code Trans § Trans 205.035

Current through November 25, 2024

Section Trans 205.035 - Use of alternative "3R" standards

(1) The standards in s. Trans 205.03 shall be used for all county trunk highway improvement projects, unless a region director expressly authorizes, in writing, the use of the department's "Design Criteria for Resurfacing, Restoration, and Rehabilitation Projects," also known as "3R" standards, for a resurfacing, restoration, or rehabilitation project on an existing highway located in his or her region.

Note: Examples of improvement projects which may be appropriate for "3R" standards include resurfacing highway pavement; grinding and repairing pavement joints; replacing or recycling pavement; widening lanes and shoulders; replacing bridge elements to correct structural deficiencies; bridge deck overlays; and other related improvements such as minor incidental subgrade work and correction of minor drainage problems.

(2) A region director may not authorize or approve the use of the department's "3R" standards for the construction of a new highway or for the complete reconstruction of an existing highway.

(3) A request to use the department's "3R" standards in lieu of the standards in s. Trans 205.03 may be submitted to a region director only by a county highway commissioner, or by a county highway commissioner's designee.

(4) A region director shall grant or deny a request to use the department's "3R" standards within 90 days after receiving a request.

(5) In determining whether to grant or deny a request to use the department's "3R" standards in lieu of the standards in s. Trans 205.03, a region director shall consider all of the following:

(a) Adequacy of design.

(b) Cost effectiveness.

(c) Safety improvement.

(d) Environmental impact.

(e) Social and economic impact, including dislocation or relocation of property owners.

(6) The rural county trunk highway minimum "3R" standards for roadway dimensions, by functional classification, and usable bridge widths are as shown in the following tables:

TABLE (A)- ARTERIALS*

TRAFFIC VOLUME		ROADWAY WIDTH DIMENSIONS IN FEET
Design Class	Design ADT	Design Speed MPH	Traveled Way	Shoulder	Roadway
3RA1	Under 750	55	22**	3	28
3RA2	750-2 000	55	24	4	32
3RA3	Over 2000	55	24	6	36

*Minimum design standards for sight distance, horizontal alignment and vertical alignment shall conform with applicable department of transportation criteria.

**A traveled way width of 24 feet is required on federally designated long truck routes and is desirable on state designated truck routes and non-designated routes where the current heavy vehicle (six or more tires) traffic volume is more than 10 percent of design ADT.

TABLE (B)-COLLECTORS AND LOCALS*

TRAFFIC VOLUME		ROADWAY WIDTH DIMENSIONS IN FEET
Design Class	Design ADT	Design Speed MPH	Traveled Way**	Shoulder	Roadway
3RC1	Under 750	55	20	3	26
3RC2	750-2000	55	22	4	30
3RC3	Over 2000	55	22	6	34

*Minimum design standards for sight distance, horizontal alignment and vertical alignment shall conform with applicable department of transportation criteria.

TABLE (C)-BRIDGE WIDTH*

DESIGN ADT	USABLE BRIDGE WIDTH IN FEET**
0-750	Traveled way
751-2000	Traveled way plus 2 feet
2001 - 4000	Traveled way plus 4 feet
Over 4000	Traveled way plus 6 feet

*Bridge replacement or widening should be evaluated if the bridge is less than 100 feet long and the usable width is less than the values in the table.

**If lane widening is planned as part of the "3R" project, the usable bridge width should be compared with the planned width of the approaches after they are widened.
