About Bridge Projects
Types of Bridge WorkBridges of different condition levels require different types of repairs. The following are a number of types of work that will be completed through the Accelerated Bridge Program.
Bridge Repairs and MaintenanceBridges constantly undergo maintenance work to ensure bridges remain in sound condition. Maintenance activities include washing (to ensure debris and other materials do not contribute to the corrosion of the steel and concrete elements of the structure), cleaning and painting of structural steel, lubrication of bearings, cleaning of debris, sealing joints, and asphalt repairs contribute to the health and love of service of a bridge.
Bridge PreservationBridge preservation projects address minor structural issues noted during bridge inspections before problems become costly. Preservation work requires little if any design and engineering work.
Minor Bridge Rehabilitation and BettermentsMinor bridge rehabilitation and betterment projects address bridges that are generally in good condition but have limited deterioration making a bridge structurally deficient. Typically, limited rehabilitation or betterment projects repair deterioration allowing a bridge to move out of structural deficient status. Work may include deck replacement, safety upgrades, and increases to carrying capacity.
Major Bridge RehabilitationMajor bridge rehabilitation projects address components of bridges which have deteriorated significantly. Rehabilitation involves replacement of major bridge elements such as superstructure, along with upgrades to meet modern bridge codes.
Bridge ReplacementBridge replacement is required when deterioration of a bridge is so significant that the structure has reached the end of its service life. This is chosen when rehabilitation of individual bridge components is more costly than complete bridge replacements.

ABP UpdateThrough August 1, 2013 the MassDOT Accelerated Bridge Program has advertised 179 construction projects with a combined construction budget valued at $2.16 Billion.
Of these 179 advertised construction projects:
- 140 have already, or will, repair/replace 259 bridges throughout the Commonwealth.
- 39 are maintenance/preservation projects which provide work to improve the safety of many additional bridges in the Commonwealth.
- 177 have been awarded to a contractor.
- 138 have been declared complete by MassDOT (or DCR) with two additional contracts terminated and the remaining scope transferred to other contracts.
