This data set was available on the Montana State Library web site until June 2015, when it was replaced by a new version of the data.

The Twin Bridges Database consists of town limits, water system infrastructure, wastewater infrastructure, stormwater drainage infrastructure, parks, and trails within the Town of Twin Bridges. Data layers are organized in a file geodatabase. The AutoCAD Feature Dataset contains the original AutoCAD layers. The BaseLayers Feature Dataset contains the TownLimits Feature Class. The Recreation Feature Dataset contains the Parks and Trails Feature Classes. The StormwaterSystem Feature Dataset contains the STSDropInlets, STSManholes, and STSPipe Feature Classes. The WastewaterSystem Feature Dataset contains the BlowOffValve, CleanOuts, IrrigationPivots, Lagoons, Lift Stations, Manholes, and WWPipe Feature Classes. The WaterSystem Feature Dataset contains the FireHydrants, Pipe, Valves, WaterTanks, and Wells Feature Classes.

AutoCAD data of town infrastructure was scaled, rotated, shifted, and "rubbersheeted" to match parcel boundaries from the Montana Cadastral Framework created by the Montana State Library as closely as possible. Several additions were made from hard copy reports and town staff knowledge. The resulting data is for planning purposes only. Field surveys and other methods are needed to find exact locations of infrastructure.
The purpose of the Twin Bridges Database is to organize and maintain spatial data for the Town of Twin Bridges.
