This latest, annual Work Plan describes all of the projects and activities that the Maine Department of Transportation (MaineDOT) plans to undertake over the next three years. It describes all work planned to be done by, or under contract for, MaineDOT during that time frame, including major construction projects for all transportation modes; smaller construction and maintenance projects; plowing and summer road maintenance; bus, rail and ferry operations; sidewalks and trails; and more. The Work Plan documents what we plan to do, and provides a tool for you, our customer, to assess how well we are performing our mission: To responsibly provide our customers the safest and most efficient transportation system possible, given available resources.Developing the Work Plan requires significant effort all across the department. We begin by estimating the federal, state, local and private funding resources we anticipate will be available, knowing that they may change over the life of the plan. Meanwhile, planners and engineers continuously monitor and measure the condition of Maine's ever-changing transportation system. With those foundations, we use data-driven processes to select projects and activities, striving to optimize the planned work so we can make the best of every available dollar.The estimated value of work in this Work Plan totals more than $2.0 billion, with some 1,929 work items to be performed over three years. The projects and activities listed for Calendar Year (CY) 2015 are more firmly funded and with definite schedules, while listings for CYs 2016 and 2017 are more subject to changes that may be needed due to future fluctuations in funding and prices, permitting variables and seasonal weather conditions. The CY 2015 work includes 523 capital projects with a combined total value of $469 million, including the following work, shown with approximate estimated costs: Replacement or rehabilitation of 47 Bridges, at a total estimated value of nearly $95 million.  Construction, reconstruction or rehabilitation of 82 miles of state-jurisdiction roads, at a total estimated value of $122 million.  Paving to preserve the investment on 252 miles of high-priority, improved roads, at a total estimated value of about $86 million.  Light capital paving (LCP) to keep 600 miles of lower-priority roads serviceable, at a total estimated value of $28 million.  76 highway spot and safety projects, at a total estimated value of $30 million.  94 multimodal capital projects to improve ports, rail, airports, transit facilities and other modes of transportation, with a total estimated value of $72 million. The first is the significant investment we are making in Maine's economy. In addition to maintaining a healthy highway and bridge system, we are continuing to make strategic investment in our ports, freight-rail and aviation facilities-all targeted to improve access and lower transportation costs for the businesses that employ Maine people and help grow our economy.
