                GRANITE CONSTRUCTION REAFFIRMS POSITIVE OUTLOOK;
                 PROVIDES UPDATE ON FULL YEAR 2006 EXPECTATIONS

     WATSONVILLE, Calif., Sept. 20 /PRNewswire-FirstCall/ -- Granite
Construction Incorporated (NYSE: GVA) today reaffirmed its positive outlook for
the Company's financial performance in 2006. The Company reported that demand
for its construction services and aggregate materials continues to be very
strong in the West. The Branch Division is experiencing healthy public sector
bidding opportunities, as well as private non-residential commercial and
industrial work. The Company continues to expect the Branch Division to deliver
2006 operating income that exceeds the record performance set in 2005.

     As an update to its previously stated guidance on July 26, 2006, the
Company no longer expects operating results for the Heavy Construction Division
to reach break-even this year. The division's year-end results will be dependent
on several projects reaching the threshold for profit recognition, the amount of
revenue received from outstanding claims and change orders, as well as the
operating performance for the remainder of the year.

     Given the Branch Division's positive outlook and record results through the
first half of the year, the Company continues to expect total company earnings
results in 2006 to exceed 2005.

     Granite will announce its third quarter 2006 results after the close of
market on Wednesday, October 25, 2006. A conference call will be held at 11:00
am EDT on Thursday, October 26, 2006.

     Granite, a member of the S&P 400 Midcap Index, the Domini 400 Social Index
and the Russell 2000, is one of the nation's largest diversified heavy civil
contractors and construction materials producers. Granite Construction serves
public and private sector clients through its offices nationwide. For more
