GIVEN S30,OO0 MORE. ID FINISH TEMPE AVD
 AGUA FRA BRIDGES

An additional emergency appropria tion of S30,00O has been granted by Governor Thomas E. Campbell to cover the construction work on the Tempe and Agua Fria bridges.
 Several months ago $100,000 was al- loted for the work, but at the time this amount was granted the state highway department had not been full Iy advised as to the amount of repairs
 These repairs of the Tempe bridge, according to Thomas Maddock, state engineer are merely temporary, a statement he made some time ago when he announced that the bridge was too light for modern traffic. He again makes the charge. declaring that the bridge will have to be greatly strengthened in order to insure life beyond the next few years.
 Mir. Maddock says that the cost of work at the Tempe bridge has been increased by the desire of the highway department to keep traffic moving over the bridge during constructions at a saving each month of between S15,- 900 and $1O0,0 He bases his esti- mate on the fact that the bridge Is used daily by approximately 5,OOO vehicles at a saving of fully of S1 each from making the longer trip from Phoenix to Tempe by the way of South Central avenue.
 This point is set forth in a letter to Governor Campbell who yesterday
  repairs on the Tempe bridge and S1o,- 900 for repairs of the Agua Fria bridge.
 The letter in full follows:
 Hon. ThoS. F. Campbell.
 Governor Arizona,
 State House. City
 Dear Sir:
 We are hereby requisting an addi- tional emergency appropriation or $30,000 to cover additional construction A TNr-isl bridges, for which construction $10O,- 900 was allotted several months ago.
 At the time of our former request we were not fully advised as to the extent of the repairs necessary. We at that time notified you that the $100,OO0 was merely an estimate. We are sorry that we cannot even assure you that the additional $30,0O0 will complete this work but, in our opinion, this estimate of the amount necessary to complete the work is much closer than tue original estimate
 Subsequent to your providing $1OO,- 900 for the Tempe bridge repair work, an additional settling of the pier oc- cured This has caused us to change our plans and, at the present time, we will install six additional caissons instead of four in strengthening the two caissons in the original construc- ton. This has resulted in 50 per cent increase in the cost Of portion of the sub b-structure work
 We also have repaired many more shattered columns and much more of the deck slab than was originally con- templated, as the destruction was greater than appeared on tie surface.
 Our inability to secure steel sheet piling has compelled the use Of wooden Wakefield piling which has in creased our cost and also reduced the speed of this construction.
 The delay in the work on the Tempe bridge, as well as the delay of nearly six months in securing the heavy tim bers necessary for the construction of the bridge at Cold Water across the Agua Fria, have resulted in consider able overhead costs which, together with the guarding of the property have increased our total costs.
 The material for Agua Fria bridge has finally arrived and this work should proceed to an early com pletion. While our work on the Tempe bridge has progressed much slower than we would have desired, this construction should be complete before the next high water in the Salt River unless unusual conditions pre- vail
 The cost of the work at Tempe has been somewhat increased by our desiring to keep traffic moving over the bridge during construction. AS this bridge is used daily by approxi- mately 5000 vehicles at a saving of fully $1 a piece on making the longer trip from Phoenix to Tempe by the way of South Center street, we feel that the taxpayers are being saved probably between 75 and 100000 dol lars for each months time this bridge can be kept open. This means that
