	KNOW ALL PERSONS BY THESE PRESENTS, that the undersigned
 hereby makes, constitutes and appoints James H. Roberts, Richard
 A. Watts and Betty Kwong, and each of them, as the undersigned?s
 true and lawful attorney-in-fact (the ?Attorney-in Fact?), with
 full power of substitution and re-substitution, each with the
 power to act alone for the undersigned and in the undersigned?s
 name, place and stead, in any and all capacities to:

	1.	prepare, execute and file with the Securities and
 Exchange Commission, any national securities exchange or securities
 quotation system and Granite Construction Incorporated (the ?Company?)
 any and all reports (including any amendment thereto) of the
 undersigned required or considered advisable under Section 16(a)
 of the Securities Exchange Act of 1934 (the ?Exchange Act?) and the
 rules and regulations thereunder, with respect to the equity
 securities of the Company, including Forms 3, 4 and 5; and

	2.	obtain, as the undersigned?s representative and on
 the undersigned?s behalf, information regarding transactions in the
 Company?s equity securities from any third party, including the
 Company and any brokers, dealers, employee benefit plan administrators
 and trustees, and the undersigned hereby authorizes any such third
 party to release any such information to the Attorney-in-Fact.

	The undersigned acknowledges that:

	1.	this Limited Power of Attorney authorizes, but does not
 require, the Attorney-in-Fact to act at his or her discretion on
 information provided to such Attorney-in-Fact without independent
 verification of such information;

	2.	any documents prepared or executed by the Attorney-in-
Fact on behalf of the undersigned pursuant to this Limited Power of
 Attorney will be in such form and will contain such information as the
 Attorney-in-Fact, in his or her discretion, deems necessary or desirable;

	3.	neither the Company nor the Attorney-in-Fact assumes any
 liability for the undersigned?s responsibility to comply with the
 requirements of Section 16 of the Exchange Act, any liability of the
 undersigned for any failure to comply with such requirements, or any
 liability of the undersigned for disgorgement of profits under Section
 16(b) of the Exchange Act; and

	4.	this Limited Power of Attorney does not relieve the
 undersigned from responsibility for compliance with the undersigned?s
 obligations under Section 16 of the Exchange Act, including, without,
 limitation, the reporting requirements under Section 16(a) of the
 Exchange Act.

	The undersigned hereby grants to the Attorney-in-Fact full power
 and authority to do and perform each and every act and thing requisite,
 necessary or convenient to be done in connection with the foregoing,
 as fully, to all intents and purposes, as the undersigned might or could
 do in person, hereby ratifying and confirming all that the Attorney-in-
Fact, or his or her substitute or substitutes, shall lawfully do or cause
 to be done by authority of this Limited Power of Attorney.

	The execution by the undersigned of this Limited Power of Attorney
 hereby expressly revokes and terminates any powers of attorney previously
 granted by the undersigned with respect to the preparation, execution and
 filing of reports of the undersigned under Section 16(a) of the Exchange
 Act and the rules and regulations thereunder with respect to the equity
 securities of the Company.  This Limited Power of Attorney shall remain
 in full force and effect until the undersigned is no longer required to
 file Forms 4 or 5 with respect to the undersigned?s transactions in equity
 securities of the Company, unless earlier revoked by the undersigned in a
 signed writing delivered to the Attorney-in-Fact.

	This Limited Power of Attorney shall be governed and construed in
 accordance the laws of the State of California without regard to conflict-
of-law principles.

	IN WITNESS WHEREOF, the undersigned has executed this Limited Power
 of Attorney as of this 6th day of June 2018.
