Exhibit 31.1
 CERTIFICATION
PURSUANT TO RULES 13A-14 AND 15D-14
OF THE SECURITIES ACT OF 1934
  1.
    
    I have reviewed this Annual Report on Form 10-K for the fiscal year ended
December 31, 2007 of Meadow Valley Corporation (the Report);2.
    
    Based on my knowledge, the Report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements made,
in light of the circumstances under which such statements were made, not misleading
with respect to the period covered by the Report;3.
    
    Based on my knowledge, the financial statements, and other financial
information included in the Report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as of, and
for, the periods presented in the Report;4.
    
    The registrants other certifying officer(s) and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in Exchange
Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
 a)
    
    Designed such disclosure controls and procedures, or caused
such disclosure controls and procedures to be designed under our supervision,
to ensure that material information relating to the registrant, including its
consolidated subsidiaries, is made known to us by others within those entities,
particularly during the period in which the Report is being prepared;b)
    
    Designed such internal control over financial reporting, or
caused such internal control over financial reporting to be designed under our
supervision, to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles;c)
    
    Evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in the Report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
period covered by the Report based on such evaluation; andd)
    
    Disclosed in the Report any change in the registrants internal
control over financial reporting that occurred during the registrants most
recent fiscal quarter (the registrants fourth fiscal quarter in the case of an
annual report) that has materially affected, or is reasonably likely to
materially affect, the registrants internal control over financial reporting.
 5.
    
    The registrants other certifying officer(s) and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
registrants auditors and the audit committee of the registrants board of directors
(or persons performing the equivalent functions):
 a)
    
    All significant deficiencies and material weaknesses in the
design or operation of internal control over financial reporting which are
reasonably likely to adversely affect the registrants ability to record,
process, summarize and report financial information; andb)
    
    Any fraud, whether or not material, that involves management or
other employees who have a significant role in the registrants internal
control over financial reporting.
