WOBURN — As part of Massachusetts Port Authority’s program offering transportation to and from Boston Logan International Airport, MassPort will be adding an additional early morning Logan Express trip from three of its most popular locations on weekdays.

Beginning Oct. 17, a new 2:15 a.m. trip from the Braintree, Framingham and Woburn Logan Express sites on weekdays will be added to the existing schedule as a pilot program.

“As Massport continues to work to connect Massachusetts with the world, we know the first step — connecting our customers and employees from their homes to the airport — is critically important,” said Massport CEO Thomas Glynn. “Logan Express has been a vital tool in improving HOV transportation utilization and we look forward to offering even more options to our customers.”

Since its beginning in 1985, Logan Express has become a centerpiece of Massport’s commitment to improving high occupancy vehicle (HOV) transportation options to and from New England’s largest airport to reduce traffic congestion, pollution and parking needs. The service started with one route and served 10,000 passengers in two months in 1985. In 2015, Logan Express served five routes and carried nearly 1.8 million passengers.

Logan Express is an option for airline passengers and airport employees throughout Eastern Massachusetts with daily trips to and from Back Bay, Braintree, Framingham, Peabody and Woburn. With the 2:15 a.m. departures, Logan Express will provide nearly round-the-clock service. On weekdays, the last buses leaving Logan for Braintree, Framingham and Woburn depart the airport at 1:15 a.m.

Since 1990, Massport has provided more than $100 million to expand HOV options: $65 million for five Logan Express locations from Braintree, Framingham, Woburn, Peabody and Boston Back Bay; $10 million per year to operate Logan Express including $1.8 million annual to subsidize Back Bay Logan Express; $20.5 million for purchase and midlife rehab of eight Silver Line buses for the MBTA; $1 million per year to provide free Silver Line service from Logan Airport to South Station for passengers; and $38 million to replace diesel buses with a clean fuel shuttle bus fleet and operate it between Logan terminals, the Rental Car Center and MBTA Blue line.

As a result, HOV options to Logan Airport have more than doubled since 1990, from 8,000 seats in 1990 to 20,450 seats in 2015. Those needing to get to and from the airport have utilized these options in droves: 30 percent of all Logan Airport passengers use HOV options, one of the highest rates in the country.
