"Traffic improvement plan to cost $37,500,000, council told: Commission's report urges varied list of big projects: Preliminary estimate virtually final, experts say: Suggest new Northside span." Pittsburgh Post, Dec. 29, 1925, pp. 1–2. Newspapers.com 88707352, 88707354.
A rough estimate of $37,500,000 is placed as the cost of developing the inter-district traffic circuits and attendant improvements proposed by the citizens' committee on city plan, in a report submitted to council yesterday by the city planning commission which has conducted a study of the original study, embracing as it does wide range of the major street plan.
While the report was submitted as one of preliminary character, its authors stated that it was to be regarded as final except as to estimates of cost which only can be placed outside the tentative range when work is undertaken and existing realty values and labor conditions are more definitely determined.
TRAFFIC PLAN ELABORATE.
The plans considered by the commission affect many street widenings and other major improvements which have been advocated in various form over the years, but tangibly developed by the more recent plan of the committee. The traffic circuit, which is an elaborate thoroughfare layout affecting the downtown, Northside and Southside, and co-ordinates present extensive developments, such as the Liberty bridge, was presented to council some months ago in large pictorial form by the citizens' committee. The large picture was placed in the lobby of the City–County building and council appropriated a fund for an analysis of the detail involved.
The plan is given the indorsement of the city planning comission [sic], which then enters into detail, grouping the various improvements as to cost, and recomending progressive construction through bond funds and an enlargement of the benefit assessment system. The inter-district traffic circuit is pointed out as a vital need by the report, as its benefits will be extended to all sections of the city.
CO-OPERATE WITH COUNTY.
The reports presents the group form as a means of carrying out improvements closely related and each group is designed to be a logical part of a continuous financial program.
The city's 1919 bond issue of $22,000,000 and that of the county in 1924 making an aggregate of $50,000,000 are referred to as representing authorized expenditure comparative with the proposals under the plan considered. The whole plan is closely meshed with the general plan of the county road system.
One of the features of the inter-district plan is a bridge terminating at the Bigelow boulevard and a point in the Northside in practical alignment with Eleventh street.
VIADUCT IS PROPOSED.
It would be continuance of the northerly course of the Liberty tubes and bridge, a cross-town viaduct connecting the proposed and the Liberty bridge. This connection would be a valuable addition to the county road system connecting the north and south systems which at present are gapped by the city. On this account the commission has the thought that the county would finance the bridge and viaduct.
Among the projects advocated are a traffic circle at the Point, widening of Duquesne way, Water street, Grant street, Liberty avenue, Fifth avenue, Forbes street, Allegheny avenue, North avenue, Chestnut street and Carson street, a connection between Irwin and North avenues and Brighton road, a complete new Baltimore & Ohio railroad, an underpass to carry westbound Carson street traffic under the south end of the new Point bridge and elevated roadway above Carson street between the Wabash railroad bridge and Brownsville avenue is suggested.
This list of improvements entail a mass of interlocking improvements, for instance the Water and Duquesne way widenings involve a quay or wharf wall enclosing the triangle from Smithfield street to Tenth street on the Allegheny river, an item estimated to cost $5,500,000. The widening of the two streets is estimated to cost $653,000.
URGE CONTINUED STUDY.
While the report is one of many pages and includes a vast amount of technical detail, the commission makes no representation that the study is complete as it urges a continuance in the following excerpt:
"It is recommended that the present study be continued. This is desirable and important so that there may be opportunity for public utility companies and others to confer with the city planning commission and other city departments with reference to adjustment of their facilities and properties to those public facilities which are embraced in the inter-district traffic circuit plans.
"In the meantime, the city planning commission is prepared to recommend the gradual execution of the whole inter-district traffic circuit project.
"Financial conditions and factors having to do with the organization and execution of construction programs both indicate that the entire project will have to be undertaken by stages and progressively pursued until the completion of the whole. Expenditures for future public improvements being cumulative in any case, the planning commission has recognized this fact, and, as noted in Section One, has subdivided the entire project into various construction sections or stages. These stages are adapted to progressive initiation and their estimated costs appear to be reasonably well-adjusted to the practicability of a continuing financial program."
NEW BRIDGE SUGGESTED.
The commission adds there is nothing in the recommendation for progressive development of the traffic circuit to interfere with other improvements for which there may be urgent public demand as the progressive order can be interrupted.
The commission emphasizes the need of keeping traffic flowing and outlines proposed intersection enlargements and traffic circles. At the junction of the Point and Manchester bridge ramps a circle 220 feet in diameter is proposed. The development of the wharves entail new harbor lines, double roadways on Water street and a roadway on Duquesne way. The proposed connection with the Northside would entail another bridge across the Allegheny river with terminal at Ohio street. All the railroads are involved by the plans which recognize traffic demands as paramount.
Other than receive the report council took no action on it.
