State leaders and family of Petty Officer Danny Dietz will gather for a ceremony Tuesday to honor the Commando, killed in the line of duty.
They will dedicate a stretch of South Sante Fe Drive in Denver in Dietz's memory.
The major commuter thoroghfare will bear the name Petty Officer Danny Dietz Memorial Highway.
Dietz grew up in Littleton and graduated from Heritage High School in 1999.
He was killed in action in Afghanistan in 2005 in a gun battle with Taliban forces.
His unit was ambushed, outnumbered, and surrounded by Taliban fighters when Dietz fought his way to the top of a hill to call for assistance.
He kept firing at enemy forces, despite being injured. He finally fell down, mortally wounded.
The U.S. Military says Dietz fought off attackers for more than 45 minutes, allowing one of his fellow commandos to escape.
He was posthumously awarded the Navy Cross, the Navy's second highest medal.
Littleton Republican State Senator Mike Kopp introduced Senate Joint Resolution 33 that made the dedication possible.
He is a former Army Ranger, and will attend the ceremony.
State Rep. Joe Rice of Littleton serves in the Army Reserve and carried the resolution in the House of Representatives. He was also be in attendance.
