BOSTON (AP) -- Massachusetts legislative leaders are making the unusual move of announcing a joint House-Senate transportation financing plan.

Leaders including Senate President Therese Murray and House Speaker Robert DeLeo, both Democrats, are scheduled to attend the announcement scheduled for Tuesday morning.

The plan will identify and solve the current transportation funding gap, require state agencies to meet reforms and provide adequate revenue to enable future capital investments.

Democratic Gov. Deval Patrick has already proposed a series of tax reforms he says will raise nearly $2 billion for transportation and education initiatives.

Patrick filed a transportation bond bill last month he says will help pay for needed road, bridge and public transit projects.

The governor called for a 10-year, nearly $14 billion plan that will spur economic growth and create jobs.
