From PennDot:
The portal, http://data.pennshare.opendata.arcgis.com/, leverages a GIS platform used in several states and helps local government, planning and business partners as well as the public. The data, grouped by roadways, bridges, rail, facilities, boundaries and projects, can be used for mapping, sharing, charting and more.

The majority of the available data is updated daily, with some more static data such as boundaries, facilities and railway receiving periodic updates. The site is compatible with any device or platform.[Clip]Data available for PennDOT’s construction projects is also used through the department’s projects website, www.projects.penndot.gov, which was launched last year to increase public information and transparency on active projects and those in the department’s Four and Twelve Year Plans.
In addition, the public can request access to PennDOT’s real-time, streaming video from its more than 700 traffic cameras as well as its Road Condition Reporting System Data, which provides real-time traffic incident, roadwork and other data. Information on these feeds is available at www.penndot.gov under “Doing Business” by selecting “Online Services” and “Developer Resources.”
The site follows the state Department of Conservation and Natural Resources announcement this month of the availability of their data through the same GIS platform, http://data.dcnr.opendata.arcgis.com.
