(a) The necessity for the project;
(b) The approval of the location and the engineering plans, including provisions for handling traffic during construction and the work to be performed by each party; and
(c) The sum to be advanced by the applicant or the account for the work to be done by the respondent.
(2) The Department of Transportation shall render as promptly as possible an interim order, effective within 20 days on such questions, reserving for later hearing and decision the question of the apportionment of costs. The interim order shall also direct the respondent to proceed upon receipt of the sum to be advanced by the applicant or the account without delay to perform the work to be done by respondent, integrating the work with that of the applicant or its contractor in such manner that neither will unreasonably obstruct or delay the work of the other, to the end that the people of the state may have the use of the project at the earliest possible date.
(3) In the final order apportioning costs, the sum advanced by the applicant or the account shall be credited against its share of the costs. In the final order there shall also be credited against applicant’s share of the costs any increase in the costs found by the Department of Transportation to be directly attributable to respondent’s willful failure or refusal, after the effective date of the interim order, to proceed with its own work or to integrate the work with that of applicant or its contractor.
