DRAFT 2010-2013 STATEWIDE TRANSPORTATION IlVIPROVEMENT PROGRAM <br />APPENDIX 2 <br />STIP WORK TYPE DEFINITIONS <br />The following are work type definitions used to identify specific projects in the STIP. Each cate- <br />gory includes examples of elements that may be used to accomplish the goal. The list of exam- <br />ples is not necessarily exhaustive. <br />Modernization <br />Improvements to accommodate existing traffic and/or projected traffic growth. Primary goal is <br />to add capacity. <br />^ Addition of lanes: High Occupancy Vehicle (HOV) lanes, new alignments, new facilities <br />(bypasses) <br />^ Highway reconstruction with major alignment improvements or major widening; grade sepa- <br />rations <br />^ Widening of bridges to add travel lanes <br />^ New safety rest areas <br />Safety <br />An investment program focused on improvements to address priority hazardous highway loca- <br />tions and corridors, including the interstate, in order to reduce the number of fatal and serious <br />injury crashes. Projects funded through this program meet strict benefitlcost criteria. <br />^ Capital improvements, such as passing lanes, turn lanes, and wider shoulders <br />^ Access management <br />^ New guardrails <br />^ Illumination, delineation, or signing <br />^ Channelization within the existing roadway at intersections <br />^ Continuous shoulder rumble strips <br />^ Enforcement of traffic laws <br />^ Railroad crossing improvements (separate funding source) <br />Pavement Preservation <br />Improvements to rebuild or extend the service life of existing facilities, and rehabilitative work <br />on roadways. Preservation projects add useful life to the road without increasing the capacity. <br />^ Pavement overlays (including minor safety and bridge improvements) <br />^ Interstate Maintenance (IM) Program (pavement preservation projects on the interstate sys- <br />tem) <br />^ Reconstruction to re-establish an existing roadway <br />^ Resurfacing projects <br />Bridge <br />Improvements to rebuild or extend the service life of existing bridges and structures beyond the <br />scope of routine maintenance. <br />^ Rehabilitation, replacement, major repair <br />^ Major maintenance <br />^ Overpass screening <br />^ Tunnels <br />Page 223 <br />
