Pavement Width. 10.5.5 Length and width of pavement crossing. Indicate whether crossing is to be bored or cut, depending upon type of construction.
Pavement Width. The width of the roadway will only be a consideration on projects that have an overlay applied as part of the preventative maintenance project. For these types of projects the following applies: Interstate – Provide no less than 38 ft width w/5:1 surfacing inslopes. In mountainous terrain, a reduced shoulder width resulting in an overall top width of 36 ft w/5:1 surfacing inslopes may be considered. NHS – If the existing width exceeds the width described in the “Design Guidelines” memo dated August 5, 2008 (these widths are equal to the AASHTO roadway widths for arterials), reduce the top width to accommodate the overlay. If the resulting width will be less than the “Design Guidelines” width, steepen surfacing inslopes to no steeper than 4:1 before reducing the width. If the overlay cannot be accommodated by steepening the surfacing inslopes reduce the width to a minimum of 28 ft. If the placement of the overlay will result in a top width less than 28 ft., employ the Roadway Width Decision Process to determine if a lesser width can be utilized. STP (Primary) - If the existing width exceeds the width described in the “Design Guidelines” memo dated August 5, 2008 (note that these widths are different that the AASHTO roadway widths for collectors), reduce the top width to accommodate the overlay. If the resulting width will be less than the “Design Guidelines” width, steepen surfacing inslopes to no steeper than 4:1 before reducing the width. If the overlay cannot be accommodated by steepening the surfacing inslopes reduce the width to a minimum of 28 ft for ADT > 300, or a minimum of 24 ft. for ADT < 300. If the placement of the overlay will result in a top width less than 28 ft., employ the Roadway Width Decision Process to determine if a lesser width can be utilized. Widths less than 24 ft are not acceptable. STP (Secondary) – Maintain the applicable Geometric Design Standards width with no steeper than 4:1 inslopes. If the existing width is less than standard, provide a minimum width of 28 feet or a minimum of 24 ft. for ADT < 300, with no steeper than 4:1 inslopes. For all routes, the use of a roadway width narrower than the widths described above must be approved through the formal design exception process.
Pavement Width. Pavement width measured from face of curb to face of curb shall not be less than the following: Street Classification Pavement Width Local L2.1 Collector C2.1 Arterial A2.1 Collector C2.2 Arterial A2.2 Arterial A4.0 8.5 m 9.0 m 10.0 m 11.0 m 14.0 m 12.5 m
Pavement Width a. Major streets — Forty-four feet (44') to sixty-four feet (64') between back of curbs.
Pavement Width. 1) Residential streets — 24 feet edge to edge.
