Roadway reports by request

The following reports contain roadway geometric data in various forms, including horizontal and vertical alignment, road life (contract history) and highway classification.

Because roadway reports are large and contain an extensive amount of data, we have provided a sample of the reports and the information they contain. To request a copy of the following reports, please contact us.

Horizontal and vertical alignment report

The Horizontal and Vertical Alignment Report contains curve data extracted from state highway construction contracts. The horizontal data includes curve direction, length, radius, central angle and super elevation. The vertical data includes vertical point of intersection, percent of grade ahead and back and curve length.

Road Life (contract history) Report

The Road Life Report contains coded historical contract information on all state routes, e.g., resurfacing, reconstruction, bridge widening and replacement, lanes added, etc. This serves as the primary data source for the Washington State Pavement Management System (WSPMS), which assists pavement managers in forecasting highway construction projects.

Highway Classification Log

The Highway Classification Log is a listing maintained in Transportation Information and Planning Support (TRIPS), which includes information about items such as control section, city and county, legislative districts, federal aid class/number, maintenance area, urban area/region and Highway Performance Monitoring System (HPMS) section numbers.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
