Division Engineer Dockery agreed to recommend that the Highway Commission construct the South Jefferson overpass if the new highway right of way was secured quickly.
In early 1930, Texas Highway Commissioner Johnson and State Engineer Gibb Gilchrist visited Mt. Pleasant briefly. Citizens found out about their visit and showed them the dangerous grade crossing while they were here. They immediately saw an overpass was needed, and since they didn't need higher approval, ordered money set aside for its construction. The Highway Commission allocated $42,000 to construct the overpass on Thursday, March 20, 1930. After four years, it seemed things had finally begun to move. However, local officials would later find out that looks can be deceiving.
Highway Department engineers came to Mt. Pleasant on Tuesday, May 13 to survey for the proposed underpass. By July 24, County Judge Lazarus received a letter from Highway Department Engineer A. J. Goode of Paris stating that overpass plans, estimates, and specifications would be completed soon and sent to Austin for approval. The overpass still depended on Titus County's Commissioners obtaining right of way needed to re-route Highway 49, and the proposed highway and overpass were estimated to inject about $75,000 into Titus County when it was needed the most. On September 4, 1930, ten members of the Chamber of Commerce's City Planning Commission decided to increase interest in the overpass by recommending that the Chamber pressure the Commissioners to secure the needed right of way, and appointed a committee to meet with the Commissioners' Court to urge immediate action.
Mr. Gilchrist told a local man he thought the Highway Commission might consider starting work on the overpass without requiring the Highway 49/65 right of way. After considerable discussion, the Chamber of Commerce decided in their October 27, 1930 meeting to send Mr. Gilchrist a telegram asking him to start the overpass without having the Highway 49/65 right-of-way. H. L. Smith talked with Mr. Gilchrist and reported to the Chamber on November 3, 1930 that Mr. Gilchrist said the State would not agree start the overpass unless the Commissioner's Court signed a contract agreeing to secure right of way for Highway 49 from Highway 65 to Hart's Creek bottoms within two years, and that they would not consider another route. This being said, the Chamber appointed a committee to secure deeds for the proposed road and also for Jefferson Street beginning at the southeast corner of the square, which was part of the project. The committee started work the next morning and made substantial progress, getting several property owners' signatures.
Practically all property owners along Highway 49's proposed route signed right of way deeds, and the Commissioner's Court ordered condemnation proceedings to secure the remaining right of way west from Hart's Creek bottom to the city limits to begin in December, 1930. The commissioners asked the City to condemn land inside the city limits needed to insure that work on the overpass would be started, and wired the Highway Commission to advise them of this.
Highway Department Division Engineer Pirie visited Mt. Pleasant on April 29, 1931 and said he was certain the Highway Commission would let bids for the overpass at their next meeting. Mr. Pirie said he told commission the overpass was needed immediately, and that the order making the overpass contingent on securing Highway 65 right of way had been rescinded. The overpass project was originally connected with the Highway 49 project, and all requirements for that road had been met. The new division engineer wanted to co-operate with Titus County, and apparently had a different attitude from his predecessors. Mr. Pirie said that as soon as deeds secured for Highway 65 right of way were returned to the division office, the Highway Commission would begin graveling Highway 65 in Titus County.
By May 22, 1931, steel girders and other construction materials for the overpass furnished by the Cotton Belt had arrived and were unloaded in their machine shop yards. However, word leaked out about the same time that things hadn't gone the way they appeared. Cotton Belt surveyed the site six years before and appropriated funds for the overpass the next year. They had simply been waiting all that time on the Highway Commission to act. On January 5, 1931 the Highway Commission finally agreed to authorize the Cotton Belt to construct the overpass, except for the grading, which the Highway Department would contract. The Cotton Belt purchased all the materials needed, but the Highway Commission delayed starting the grading while they lead local officials to believe that a contract must be awarded for all of the work before any could begin.
On May 29, 1931 Engineer Gibb Gilchrist of Austin, Division Engineer Pirie of Paris, and Representative R. M. Hubbard of New Boston, a former Highway Commissioner, visited Mt. Pleasant to inspect the proposed overpass site. Some Titus County highway construction projects no longer depended on each other, and the men offered encouragement that overpass construction would begin soon.
On July 8, 1931 the City Council decided to remove sewer and water lines along South Jefferson at the overpass site and replace them with larger new lines. They changed some sewer lines along West Arizona Street and laid a six inch water main from the square to about a hundred and fifty feet south of the overpass so they could provide the south part of town with all the water they might need without tearing up the street, and to improve fire protection in the south part of town. The Council expected new houses to be built on good residential lots available in southern Mt. Pleasant due to the new road and water availability.
Overpass construction contracts were awarded on Monday, July 20, 1931. The overpass was to be 32 feet wide with a 14'6" clearance above the street. The Cotton Belt would construct the concrete and steel span using its own plans and specifications, and overpass construction would be done under the Cotton Belt engineer's supervision. L. B. George, contractor for Highway 49 grading and drainage, was awarded the overpass dirt work contract. He sublet the excavation to H. L. Hess and John B. Stephens, Sr., who performed all grading from the southeast corner of the square to the overpass and excavation under the railroad.
Work began Friday, August 14, 1931 when Cotton Belt's pile-driver began sinking 110 twenty-eight foot pilings to support temporary trestles to for each track to be used until the permanent overpass was complete. Dirt work on the road began Friday, September 11, 1931. Almost all temporary overpass bridge work was complete, and a steam shovel began excavating the highway underpass that morning. Grading work on Highway 49 started at one o'clock Friday afternoon when J. D. George's big steam shovel, which could do the work of several teams and scrapers, began cutting into the hill just west of the Hart's Creek bottoms.
Pouring concrete abutment footings and pillars for the east side of the overpass was completed by Saturday, September 26, 1931, but the west side had not been started. Walls to hold the heavy steel span supporting the tracks would rest on the footings and pillars once they were complete. The entire overpass had to be complete before dirt could be removed from the grade crossing, which was expected to take at least another month. The last concrete culvert on Highway 49 was almost complete, and grading the east end of the road was progressing well. It appeared that work on Highway 49 would be complete by the time the overpass was finished.
Work on the east concrete overpass abutment was finished by Wednesday, October 21, and the large steam shovel began back-filling them with dirt. Dirt work to prepare for constructing the west abutment and pillars was started and would be complete in a few days.
Setting the custom-made steel girders to support the railroad tracks began on December 4. Cotton Belt sent its big steam crane and a crew to Mt. Pleasant that afternoon to begin setting the steel. Considerable riveting and pre-assembly was required before the girders could be set on the concrete piers, but they were expected to be set by mid-December.
