36 | ASPIRE , Winter 2013 F H WA F H WA O n July 6, 2012, President Obama signed into law P.L. 112-141, the Moving Ahead for Progress in the 21st Century Act (MAP-21). This is a two-year act with funding for surface transportation programs for fiscal years 2013 and 2014, which began October 1, 2012. MAP-21 creates a streamlined, performance- based, and multi-modal program to address the many challenges facing the U.S. surface transportation system. This article provides a summary of the major funding and policies affecting the bridge and tunnel programs. Program Restructuring MAP-21 restructures core highway formula programs. Activities carried out under some pre-MAP-21 formula programs, such as, the N a t i o n a l H i g h wa y S y s t e m P r o g r a m , t h e Interstate Maintenance Program, and the Highway Bridge Program, are now incorporated into the following new core formula program structure: • N a t i o n a l H i g h w a y P e r f o r m a n c e Program (NHPP): $21.8 billion • Surface Transportation Program (STP): $10 billion • Congestion Mitigation and Air Quality Improvement Program (CMAQ): $2.2 billion • Highway Safety Improvement Program (HSIP): $2.4 billion • Railway-Highway Crossings (set-aside from HSIP): $0.2 billion • Metropolitan Planning: $0.3 billion Most of the SAFETEA-LU discr etionar y programs, including the Highways for LIFE, the Innovative Bridge Research and Deployment, and the National Historic Covered Bridge Preservation Programs, have been consolidated into broader programs. The new bridge and tunnel programs are now covered under the new provisions in section 1106 NHPP, section 1108 STP, and section 1111 National Bridge and Tunnel Inventor y and Inspection Standards. These three sections of MAP-21 that address bridges and tunnels are discussed in further detail below. National Highway Performance Program Under MAP-21, the enhanced National H i g h wa y S y s t e m ( N H S ) i s c o m p o s e d o f a p p r ox i m a t e l y 2 2 0 , 0 0 0 m i l e s c o m p a r e d to 160,000 miles pre-MAP-21 It includes the U.S. Interstate System, all principal arterials, border crossings on interstate and arterial routes, and highways that provide motor vehicle access between the NHS and major intermodal transportation facilities. The NHPP is authorized at an average of $21.8 billion per year to support the condition and performance of the enhanced NHS, for the construction of new facilities, and to ensure that investments of federal-aid funds in highway construction are directed to support progress toward the achievement of performance targets established in an asset management plan of a state for the NHS. The NHPP funds may be used for the following purposes for bridges and tunnels: • Construction, replacement, rehabilitation, preservation, and protection (including scour countermeasures, seismic retrofits, impact protection measures, security countermeasures, and protection against extreme events) of bridges and tunnels on the NHS. • Inspection and evaluation of bridges and tunnels on the NHS, and inspection a n d e v a l u a t i o n o f o t h e r h i g h wa y infrastr uctur e asset s on the NHS, including signs and sign structures, earth retaining walls, and drainage structures. • Training of bridge and tunnel inspectors. • Development and implementation of a state asset management plan (AMP) for NHS, including data collection; maintaining, updating, and licensing software; and equipment required for risk-based asset management and performance-based management. At a minimum, the state AMP must include: - a summary listing of the bridge assets on the NHS in the state and a description of the condition of those assets, - asset management objectives and measures, - performance gap identification, - life-cycle cost and risk management analysis, - a financial plan, and - investment strategies. MAP-21 establishes a performance program for maintaining and improving the NHS: • States are required to develop a risk- and performance-based asset management plan for the NHS to improve or preserve asset condition and system performance. The penalty for a state's failure to implement this requirement by the required date is a reduced Federal share for NHPP projects in that year (65% instead of the usual 80%). • T h e S e c r e t a r y o f Tr a n s p o r t a t i o n establishes performance measures for NHS bridge conditions, and system performance. States will establish targets for these measures, to be periodically updated. • M A P - 2 1 e s t a b l i s h e s a m i n i m u m standard for the condition of NHS bridges.
