A highly contested planned community may have finally hit a road block it can't get around.  

For McKinley Village to get the political support needed to be built, its developer must be willing to spend millions tunneling under the Union Pacific's main line to connect the development with Alhambra Boulevard.  

Relying on connections dumping McKinley's traffic onto 28th and 40th streets in residential neighborhoods is not going to past muster.  

But the Sacramento Bee reports an Alhambra tunnel is a costly and challenging proposal. And its not getting any leeway from the railroad which strictly forbids shutting down their tracks for any reason, at any time, period.  

That would drive the cost of the tunnel up from $7 million to $28 million, putting the entire project in jeopardy, according to developer, and former state treasurer Phillip Angelides.
