Dear Editor, Why bridges fail – about one-half of the Texas state gasoline-tax dollars fund projects other than roads. This includes 25% for education. Texas gets back only about 90% of its share of federal tax dollars, and the feds spend some 20% of the federal gas tax on transit. The Capital Area Metropolitan Planning Organization 2030 plan spends 32% on nonroad projects. The bottom line is that we would have fewer problems with roads and bridges if all the gas-tax money was used for them and the tax was indexed for inflation. It makes me doubt that there is any intelligent life among our local to federal politicians and transportation bureaucrats.
