Tackett said Byrd also secured more than $786 million for revitalization or replacement of aging National Guard facilities.
Even before the plane touched down, hundreds of people lined the 2.2-mile route where a horse-drawn carriage will take the casket to the state Capitol.
Mona Hayes of Charleston met Byrd in his U.S. Senate office during a 1987 junior high class trip to Washington, D.C.
"I just respect the man for everything he's done for West Virginia,'' said Hayes, who brought her 10-month-old son, Dakota, to see the procession.
"I just felt it would be something for him to say that he was here,'' Hayes said, pointing to her son.
Following a receiving ceremony at the Capitol, the casket will be moved to the Lower Rotunda, where a 12-hour public viewing will be held beginning at 9 p.m.
State employees worked Thursday to prepare the Capitol. A red carpet, white benches and American flag banners were installed on the Capitol's northern steps to accommodate Friday's memorial service.
President Barack Obama, Vice President Joe Biden, former President Bill Clinton, House Speaker Nancy Pelosi and Senator Majority Leader Harry Reid, D-Nev., were expected to attend.
