Ladies and Gentlemen:

     I am counsel at Phillips,  Gardill, Kaiser & Altmeyer, PLLC which regularly
represents  WesBanco,  Inc. (the  "Company") and I have acted as counsel for the
Company in connection with the preparation of the Registration Statement on Form
S-8 to be filed by the Company with the Securities  and Exchange  Commission for
the  registration  under the  Securities  Act of 1933, as amended,  of 1,000,000
shares  of the  Company's  common  stock,  par  value  $2.0833  per  share  (the
"Shares"),  offered pursuant to the WesBanco, Inc. Key Executive Incentive Bonus
& Option Plan (the "Plan").

     I have  examined  the  originals,  certified  copies  or  copies  otherwise
identified  to my  satisfaction  as being true copies of the Plan and such other
documents  as I have  deemed  necessary  or  appropriate  for  purposes  of this
opinion.

     Based on the foregoing,  I am of the opinion that the Shares have been duly
and validly  authorized  and reserved for  issuance,  and that the Shares,  when
issued under the terms of the Plan,  will be legally and validly  issued,  fully
paid and nonassessable.

     I hereby  consent  to the  filing of this  opinion  as  Exhibit  5.1 to the
Registration Statement.

                                            Very truly yours,


                                            /s/ James C. Gardill
                                            ------------------------------------
