           GRANITE CONSTRUCTION REPORTS FIRST QUARTER 2005 RESULTS

    WATSONVILLE, Calif., April 27 /PRNewswire-FirstCall/ -- Granite
Construction Incorporated (NYSE: GVA) today announced a net loss of
$8.3 million, or $0.20 per diluted share for the first quarter ended March 31,
2005.  This compares with a net loss of $9.1 million or $0.23 per share for
the same period last year.  Included in the first quarter 2004 results was a
gain on the sale of certain assets related to the Company's ready-mix concrete
business in Utah of approximately $10.0 million pre-tax (approximately
$6.0 million after-tax).

    "While most of our business is generally performing well, we did not get
the year off to as good of a start as we had anticipated.  However, our first
quarter profitability from our operating divisions improved significantly
compared to a year ago, which we believe is attributable to the work we have
done to improve operating performance throughout the company," said
William G. Dorey, Granite President and Chief Executive Officer.  "While we
realize we still have work to do, we have made significant progress over the
last twelve months.  We anticipate strong demand for our services in virtually
all of our markets and we remain optimistic that both of our divisions will
perform well in 2005."

    Operating Results
    For the first quarter of 2005, total Company revenue increased 25% to a
first quarter record $420.9 million compared with $337.0 million a year ago.
Total gross profit as a percent of revenue for the quarter increased to 6.4%
compared with 3.2% for the same period last year.

    Total Company backlog at March 31, 2005 was $2.6 billion compared with
$2.0 billion at March 31, 2004.  New awards for the first quarter 2005 include
a $178.0 million joint venture design-build toll road construction project in
Texas, a $104.4 million share of a joint venture design-build subway station
renovation project in New York, and a $34.8 million pumping station project in
Arkansas.

    Results by Segment
    Heavy Construction Division (HCD) revenue for the quarter totaled
$202.0 million versus $170.1 million for the same period last year.  HCD gross
profit as a percent of revenue increased in the quarter to 3.5% compared with
a negative 2.1% for the quarter ended March 31, 2004.  Operating loss for HCD
totaled $1.3 million compared with a loss of $11.3 million in the first
quarter 2004.  Improved results for the division were partially offset by
margin deterioration on five out of approximately 45 large projects.  The
unanticipated changes in the estimated costs to complete these projects
accounted for approximately $11.5 million in additional costs for the quarter.
HCD backlog increased $463.5 million to $2.0 billion compared with $1.6
billion at March 31, 2004.



    Commenting on HCD's results, Dorey stated, "We continue to focus
considerable attention on bidding discipline, project execution and
forecasting of our HCD projects.  Due to the nature and duration of many of
our HCD projects, it is important to appreciate that it takes time for the
improvements and changes we have been making to affect the division's
financial performance.  With that being said, we expect that the progress we
have made to date will result in bottom line improvement from HCD this year."

    Branch Division revenue for the quarter totaled $219.0 million, an
increase of $52.0 million or 31% over the same period in 2004.  Branch
Division gross profit as a percent of revenue increased for the first quarter
2005 to 9.0% compared with 8.5% in the first quarter 2004.  Operating loss for
the Branch Division totaled $1.1 million for the quarter compared with a loss
of $5.6 million a year ago.  Backlog for the Branch Division increased 22% for
the quarter to $582.8 million compared with $478.6 million at March 31, 2004.
    "The branches are beneficiaries of a strong private sector market in the
West where we continue to see demand for commercial and residential site
development work.  In addition, we are witnessing an active public sector
bidding environment in Arizona, Nevada, Utah and the Northwest.  Given no
significant change in these market conditions, the Branch Division has the
opportunity to perform at or above the impressive level they achieved in
2004," Dorey stated.
