pre-existing public road at the same site. At its northern end, section 3 tied into a recently constructed but existing portion of Deer Park Avenue creating a gap in the contract work until the beginning of section 2. Section 2 began at Lake Avenue and continued in a northerly direction for 4.63 miles. There was already an existing two-lane highway, 20 feet wide at or near the location of the section 2 work. Section 2 was to be widened to a four-lane road with 10-foot shoulders and a center mall. Under the terms of the agreement, claimant was to perform the widening and reconstruction of section 2 while traffic continued to operate over that section, without any interruption of traffic. This appeal relates to two provisions of the contract, Items 76S and 76X. These items are concerned with reimbursement by the State for claimant’s expenses in keeping the highway open during construction, and after completion, but prior to acceptance. Under Item 76S of the contract, claimant was paid a lump sum of $250,000 for the maintenance of traffic over specified parts of each section. This included part of section 3 and all of section 2. Under Item 76X claimant was to be paid a per unit amount if the State directed it to open segments of road prior to acceptance of the contract. The provision of Item 76X of this contract with respect to which claimant contends the State breached the contract, states, in part, as follows: "Under this item the Contractor shall maintain traffic and protect the public from damage to person and property whenever directed, in writing, by the District Engineer to open to public traffic any portion of new permanent mainline pavement or structures on new location or any portion of new permanent mainline pavement substantially on old location on which public traffic is not maintained during construction under Item 76. The Contractor shall also maintain traffic and protect the public from damage to person and property on any connector or ramp used by such traffic.” Pursuant to this item, the State paid claimant $25,450, and the Court of Claims increased this amount by $12,475 by adding the period from May 31, 1970 until the date of acceptance of the contract by the State of August 25, 1970. Claimant seeks additional damages for expenses under Item 76X for section 2 in the sum of $254,460, and for section 3 in the sum of $25,813.50. On November 14, 1967, the State ordered the new pavement of section 2 opened to traffic which was accomplished piecemeal, to wit, 2.4 miles on December 6, 1967, 1.7 miles on December 13,1967, and 0.2 mile on April 1, 1968. On October 16, 1969, the State ordered the new pavement of section 3 opened to traffic, which section was opened on December 2, 1969. The bid proposal called for a bid under Items 76S and 76X as to the amount of money the contractor was to be paid for the additional costs on sections 2 and 3 for expenses claimant would receive as a result of keeping section 2 and portions of section 3 open to traffic while road construction was in progress, and until the State accepted the work. Item 76S related to section
2 of the highway, and portions of section
3 for compensation for public use of the highway during construction, and claimant’s bid for such expense was $250,000 which was paid to claimant by the State. Under Item 76X, claimant was to be paid a per unit amount of $15 per lane mile day, if the State directed it to open completed segments of new roadway prior to acceptance of the work by the State. This item was to apply (a) to permanent mainline pavement or structures on new location, or (b) to permanent mainline pavement substantially on old location, on which public traffic was not maintained under Item 76S. Claimant’s main contention is that it is entitled to be paid under Item 76X for all of section 2. Under its terms, 76X did not apply to pre-existing pavement locations on which public traffic was maintained during construction. The record shows that the work on section
