 The 130th Engineer Brigade focused on bridging projects as was its specialty , but it ultimately found itself undertaking numerous different projects throughout the country for much of 2003 and into 2004 . Not all of its units were confined entirely to construction , though . The 502nd Engineer Company also conducted river patrol operations in Baghdad and <unk> . This new mission for the company was essential for force protection , troop transportation , search and cordon operations , and to protect against sabotage on fixed bridges . In September 2003 , with the inactivation of the 38th Engineer Company ( <unk> <unk> Bridge ) , the 502nd Engineer Company became a multi @-@ role bridge company with both float and fixed bridging capabilities and the only active bridge company in <unk> .
