 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

 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,

 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 12th day of December 2018.
